Sharrif Floyd's determination comes from an unusual source. (USAT Sports Images)

Florida defensive tackle Sharrif Floyd has blown analysts away all the way through the pre-draft process. He didn't participate in Florida's recent pro day due to a slight ankle injury he suffered at the combine, but Floyd got on the field on Friday, and confirmed everything we already knew, based on the tape. When he's told to go get after his goal, Floyd is a impressive force.

At 6-foot-3 and 297 pounds, Floyd is a surprisingly advanced player for his experience level (just one full season as a starter), and after starting the final 11 games of the 2011 season at defensive end, he anchored inside in 2012 and dominated nearly every opponent he faced. He put together 46 tackles, 13.0 tackles for loss, one sack in the regular season, and two in the Sugar Bowl against Louisville. The third-ranked Gators lost that game in a 33-23 upset, but Floyd had made his mark. Stack all that on top of a combine performance in which he clocked a 4.92 in the 40-yard dash, and it's easy to see why he's at the top of the list at his position.

Perhaps the most impressive aspect of Floyd's game, and this is more important than ever in an NFL that has multiple fronts and wants its linemen to move around, is the fact that he can move all around the defensive line. From end to nose tackle, he can do it all.

"I feel great, knowing that the hard part is done," Floyd told Charles Davis of the NFL Network after his workout was done. "A lot of teams like what I do, and that's a good thing. Now, it's just time to sit back, focus in the draft, and let them do what they've got to do."

As he did throughout his collegiate career, Floyd was relentless on the field, doing rep after rep in position drills. He was in great shape, and didn't seem to flag at all.

"He was fast, he was strong, and he was agile," Davis said of Floyd on the NFL Network's Path to the Draft show. "You name it, he was ready to go today."

"I wasn't going to stop until he told me to stop," Floyd said of the position drills. "I wasn't going to say, 'I'm done.'"

Colin Kaepernick's head coach doesn't want these biceps getting too much bigger. (USAT Sports Images)San Francisco 49ers head coach Jim Harbaugh is one of the most maniacally well-prepared people in the NFL, and he's been that way for a long time. It's one of the things that allowed him to play quarterback in the pros for 14 seasons and it's what has made him one of the NFL's best head coaches.

But it seems that even Harbaugh, the man responsible for the 49ers' recent turnaround and the man Mike Ditka once called "the most competitive player I ever coached," is concerned about the level of offseason preparation his current quarterback is putting in. Not that Harbaugh thinks Colin Kaepernick isn't doing enough -- quite the opposite.

[Also:Orioles win scheduling conflict battle with NFL]

Harbaugh has warned Kaepernick about becoming too yoked-up in his intense workouts, according to a story by Matt Maiocco of CSN Bay Area.

From the recent owners meetings:

"If you're just talking about weightlifting and upper-body strength, yes, I think there is that fear," Harbaugh said. "It's something we've talked about. 'I don't want you getting too jacked-up, Colin.' I want some speed, quickness, not just [flexing his chest muscles]."

Well, we're not sure how "steroidal" Kaepernick could ever look -- he's a lean-muscle guy to be sure. Certainly, it's good that Kaepernick is working his butt off, because he'll go into the 2013 season, his third in the NFL, as the team's starter on opening day for the first time. Of course, Kaepernick's receivers would prefer that his arm doesn't get any stronger.

Jonathan Cyprien may be a small-school player, but he's got a big future. (AP)

With the 2012 NFL season in the books, and the scouting combine in the rear-view, it's time to take a closer look at the 50 players we think will be the biggest difference-makers at the next level from this draft class. To that end, we're happy to continue this year's Shutdown 50 scouting reports (Hint: There may actually be more than 50). You can read last year's group here. The final 50 players were chosen and ranked based on game tape, combine and Pro Day results, overall positional value, and attributes and liabilities on and off the field.

40: Jonathan Cyprien, SS, Florida International

We continue this year's series with Florida International strong safety Jonathan Cyprien. Lightly recruited (at best) out of North Miami Beach High, Cyprien had two collegiate offers: Western Michigan and Florida International. He chose to stay closer to home and play for the Panthers, and he'll now follow former teammate and current Indianapolis Colts speed receiver T.Y. Hilton into the NFL. Hilton was able to make a pretty big splash in his rookie year, and in the right system, I think Cyprien could have an equivalent impact at a different position. Though he excelled against weaker competition, and some evaluators will ding him because he didn't always deal with stronger offenses, there's enough tape of his abilities against bigger programs (Louisville, Rutgers, Maryland, Texas A&M) to ease some of those concerns. In addition, he blew it up during Senior Bowl week -- Cyprien was obviously there to prove a point, and he left Mobile as the best safety in the group in the minds of many.

How will his skills translate to NFL success? At 6-foot-0 and 217 pounds, Cyprien has the valuable ability to play front-half and back-half coverage with relatively equal aplomb, which makes him an interesting chip in today's more advanced defenses. In addition, his experience in the slot makes him a potential every-down defender. You want versatility? In 2012, he led his team in tackles (93) and interceptions (four). You want durability and dependability? How about 45 collegiate starts in four seasons? Some NFL teams will devalue any player who doesn't light it up for one of the big schools, but as the only small-school player in this year's Shutdown 50, he's certainly transcended that stigma around here.

Pros: As a back-half pass-defender, Cyprien displays estimable speed and covers a lot of ground to make plays. Anticipates the ball well in the air, and will converge in a hurry. Runs from sideline to sideline to keep deep sideline receivers from making bigger gains after the catch. Has the potential to be an outstanding route-jumper. Big hitter in space who is exact with his tackling form when converging. Comes down from center field of in halves in two-deep coverage to make impact tackles on receivers after catches between the seams, and will force turnovers when doing so. Aggressive tackler, but not reckless -- doesn't spear with his helmet and makes an effort to use his arms and his shoulders. Good wrap-up tackler when he does it. Has the turn speed and awareness to defend back-shoulder fades and other boundary passes. Defends the slot well enough to come down in sub-packages -- would be ideal in "big nickel" three-safety packages like the New York Giants run.

You didn't think that we were finished doing podcasts with our buddy Greg Cosell of NFL Films and ESPN's NFL Matchup just because the NFL season is over, did you? Well, if you did, fear not -- we're back in the saddle (and Greg's now writing for Shutdown Corner as well) to do a new series of podcasts in which we evaluate the draft prospects by position. We've already discussed the quarterbacks and running backs in this year's class, and how it's time to talk about a very intriguing group of receivers and tight ends. Greg has taken his decades of experience, and oodles of coach's tape, and transferred both to the college side just in time for the pre-draft process.

The Shutdown Corner draft podcast with Greg Cosell: Evaluating the WR/TE class

A few words of wisdom from Mr. Cosell:

On Tennessee WR Cordarrelle Patterson: "Patterson will be drafted high solely because of his size, and his dynamic movement. I don't think he's anywhere close to being a quality receiver in terms of the subtleties of how to run routes. In fact, he's so much quicker and more dynamic with the ball in his hands, as opposed to running routes. Running routes, he's not that dynamic, because he doesn't know how to do it yet. He needs to go to a team with a very good receivers coach, and he needs to be taught how to become a receiver."

On West Virginia WR Tavon Austin: "He may be one of my favorite players in this draft, and I spent a lot of time talking about this on Twitter the other day. I would select this kid in the top 10 or 12 in the draft, and I think that this is where the league is going. I wrote about this in my last column on Shutdown Corner. The NFL has now become a passing space league in many ways, and the conventional concepts of how to use receivers -- that's a little old-school. I think Tavon Austin fits where this league is going."

On Clemson WR DeAndre Hopkins:

Star Lotulelei appears to be back on the right track. (Getty Images)

Before the heart condition that was diagnosed at the scouting combine, Utah defensive tackle Star Lotulelei was thought by most NFL analysts to be a top-3 pick in the upcoming draft, and top-10 at worst. But it was reported on February 24 that abnormalities seen in his echocardiogram -- Lotulelei's left ventricle was pumping at 44 percent efficiency compared with the normal range of 55 to 70 percent.

That put his combine drills on the shelf, and his future as a high draft prospect in doubt. There has been some speculation that Lotulelei's reading could have been related to dehydration, and Jeff Reynolds of the Sports Xchange reported in late February that Lotulelei lost 10 pounds in a three-day stretch as he prepared for the combine's frenetic schedule.

[Also: NFL's latest helmet/hit rule puts coaches in bind]

On Wednesday, Utah held its pro day, and Lotulelei got another chance to prove to NFL teams what he couldn't in Indianapolis. By all accounts, be absolutely nailed it. Multiple reports indicated that the 6-foot-3, 311-pound Lotulelei put up 38 reps on the 225-pound bench press, had a 30-inch vertical leap, ran the three-cone drill in 7.76 seconds, and the short shuttle in 4.65 seconds.

Gil Brandt of NFL.com reported that Lotulelei was cleared to work out by cardiologist Josef Stehlik, referred to Lotulelei's agent, Bruce Tollner, by the San Francisco 49ers. Lotulelei will visit Stehlik again in April. Brandt also said that Tollner didn't want Lotulelei to run 40-yard dashes due to conditioning issues, but he did anyway, clocking in at 5.31 and 5.36.

Those pro day numbers would have tied Lotulelei for first among defensive linemen with SMU's Margus Hunt and Missouri Southern's Brandon Williams in the bench press, tied with Florida's Sharrif Floyd in the middle of the pack on the vertical, and on the high side for defensive tackles in both agility tests. The 40s would have been on the low end of the scale, but the fact that he felt comfortable running them at all seems to indicate that he's on the mend.

NFL Network analyst Akbar Gbajabiamila reported that Lotulelei was just as impressive when going up against pads in position drills.

Star Lotulelei 38 reps on the bench, 3 cone of 7.76 and shuttle of 4.65. Dominated position drills w/ multiple D-Line coaches. #DoubleCheck

— Akbar Gbajabiamila (@Akbar_Gbaja) March 20, 2013

If Lotulelei gets multiple clean bills of health and the reading at the combine isn't seen to indicate a chronic condition, he could easily be the first defensive player selected in the draft, and perhaps the first player taken overall -- because the tape shows a player who is every bit that good.

E.J. Manuel cuts loose at Florida State's pro day. (AP)

From 2007 through 2012, Florida State has seen just three of its alumni called in the first round of the NFL draft -- linebacker Lawrence Timmons in 2007, cornerback Patrick Robinson in 2010, and quarterback Christian Ponder in 2011. That will certainly change in 2013, when as many as four Seminoles could be selected within the first 32 picks if they play their cards right. Cornerback Xavier Rhodes, defensive ends Bjoern Werner and Tank Carradine, and quarterback E.J. Manuel were all looking to cement their status when Florida State held its pro day on Tuesday.

[Also: NFL, NFLPA divided over team doctors issue]

Manuel, who was celebrating his 23rd birthday, may be the most intriguing prospect of the bunch. His stock has been rising since an impressive combine, and a decisive Senior Bowl week in which he was named the game's Most Valuable Player and looked very strong in practices. He was thought to be a second- or third-round prospect based solely on some fairly inconsistent game tape, but that's changed, and two events marked the transition on Tuesday. First, there was the fact that Manuel threw very well to his own receivers during a 54-play scripted throwing session. Then, he was invited to attend the draft in New York City -- an honor generally reserved for those who the NFL believes will be drafted in or near the first round. More players are invited these days, but that didn't lessen the thrill for Manuel.

"When I got the invite, I was about to cry, really, because that was probably my biggest goal," Manuel told CBS Sports. "I know there's a lot being said about me going into it, but I never listened to it."

In his 2012 season, Manuel completed 263 of 387 passes for 3,397 yards, 23 touchdowns, and 10 interceptions, leading the ACC in completion percentage (68.0) and total yards per play (7.2). He also ran for 310 yards and four touchdowns on 103 attempts, adding to his currency as a mobile quarterback. He kept the momentum rolling at Doak Campbell stadium.

"It was great," Manuel told NFL.com's Mike Mayock. "Great weather -- a little overcast this morning, but I didn't care. I just wanted to come out here and compete again, and show everybody what I can do. I think the biggest thing is just having timing with my receivers. Obviously, the pro day is built for you, so if you can't come out here and complete 95 percentage-wise [of your passes], you can't play. The biggest thing was to show my timing, accuracy, and arm strength."

He's been doing that for the last few months, but there are still concerns. As I wrote in Manuel's Shutdown 50 scouting report, he does have issues making multiple reads, throwing into zone defenses, and lining up with his receivers on throws that require anticipation. I also wonder if these shortfalls are a function of scheme, and I have posited that Manuel can acquire these skills when football is his primary priority, as it will be in the NFL.

It's been a pretty volatile offseason for former Oakland Raiders and current Cleveland Browns defensive lineman Desmond Bryant. Free agency brought him a five-year, $34 million contract with $15 million guaranteed, but he may have to spend some of that new cash in a way he'd rather not. Shutdown Corner has seen a lawsuit filed on Monday in Dade County, Fla. Circuit Court by Isaac and Iris Bakar and their three children, the people Bryant was arrested for harassing on Feb. 24.

Bryant is being sued on one count of assault, one count of intentional infliction of emotional distress, and one count of trespassing.

[Also: Tennessee Titans release Matt Hasselbeck, agree to terms with Ryan Fitzpatrick]

According to the suit filed by attorney Robert J. Fiore, P.A., the Bakar family seeks damages in excess of $15,000, exclusive of interests, costs, and attorney's fees. The suit claims that at approximately 5:30 a.m. on Feb. 24, Bryant "unlawfully trespassed onto the family property, and without provocation, legal justification, or a shirt, began hitting and pounding on the doors loudly and repeatedly. This wakened the plaintiffs, causing all to be terrified and in great fear for their safety."

It's then claimed that Mr. Bakar ran to the front doors and saw Bryant leaning on the family car just outside the home. Bryant than ran back to the front doors, pounded the doors again, and attempted to "forcibly pull the doors open in an out-of-control violent rage."

At that point, the Bakars called 911. More from the suit:

Thereafter, using his best efforts to keep the doors closed and deny the Defendant entry into the family home, Plaintiff Isaac Bakar, who stands 5 feet, 10 1/2 inches tall and weighs 170 pounds, frantically grabbed the inside door handle and held on, yelling words through the door, among others, for the Defendant to "go away" and "leave my family alone." Further, at one point, the Plaintiff yelled to the Defendant, 'what do you want, and why are you doing this to us?" The Defendant neither responded nor made his intentions known, but instead continued his relentless, violent assault on the Plaintiffs, causing Issac, Iris, and their three small children to be paralyzed with fear.

Mike Glennon throws a ball into the air. Where it goes, he knows not where. (USAT Sports Images)

With the 2012 NFL season in the books, and the scouting combine in the rear-view, it's time to take a closer look at the 50 players we think will be the biggest difference-makers at the next level from this draft class. To that end, we're happy to continue this year's Shutdown 50 scouting reports (Hint: There may actually be more than 50). You can read last year's group here. The final 50 players were chosen and ranked based on game tape, combine and pro day results, overall positional value, and attributes and liabilities on and off the field.

41. Mike Glennon, QB, North Carolina State

We continue this year's series with North Carolina State's Mike Glennon, one member of a quarterback class that has been perhaps unfairly maligned, standing in the shadows of a 2012 class that gave us Andrew Luck, Robert Griffin III and Russell Wilson. At least the 6-foot-7 Glennon is used to standing in the 5-foot-11 shadow of Wilson; he had to wait until Wilson transferred from N.C. State to Wisconsin in 2011 before he could be a starter in college. Glennon showed flashes of the ability that made him one of the most prized high school recruits in the country in 2007.

[Also: NFL, NFLPA divided over team doctors issue]

In his first year as a starter, Glennon completed 283 passes in 453 attempts for 3,054 yards, 31 touchdowns and 12 interceptions. However, the burden of production shifted far more to Glennon's shoulders in 2012, and that wasn't always a good thing. He led the ACC in interceptions with 17, while attempting over 100 more passes and throwing for over 1,000 more yards. Estimable production and frustrating mistakes? That was the snapshot view of Glennon's time in Raleigh.

At the Senior Bowl, Glennon looked great in practices, when he didn't have pass rushers bearing down on him, and he could show off his amazing throwing arm. But in the game itself, that old bugaboo of his -- severe inconsistency under pressure -- reared its ugly head. Glennon completed eight of 16 passes in the game for 82 yards, no touchdowns and a pick. Teams in love with pure physical attributes will surely value Glennon highly, but when you watch the game tape, there's a lot to worry about. The version of Mike Glennon we see in the NFL will depend a great deal on coaching, scheme and personnel.

Pros: Glennon displays a smooth and consistent dropback form on long passes that require five-and seven-stop drops. His footwork isn't choppy, and he times the rock from his back foot to the throw on his plant foot well. More mobile than he looks; will bail out of pressure, especially to his right, and make throws (though accuracy is something we'll talk about later). When moving in and around the pocket, tends to reset pretty quickly and keeps his eyes downfield. Can roll right off of boot action and make tough throws downfield. Has an easy, quick, relatively compact delivery (a little hitch when he's bringing the ball back to the side of his head), and the ball just zings off his hand.
