Perhaps the most interesting thing about the two tight ends almost universally regarded as the best 2010 prospects is that neither one of them played a single down in 2009. Between the knee injury suffered by Jermaine Gresham and the back problems that Rob Gronkowski has been dealing with, anyone with a desire to put together comprehensive reports on these players has to go back to 2008. It's a worthy endeavor in both cases, as both players have the potential to define NFL offenses if they can set their medical concerns aside:

Jermaine Gresham, Oklahoma Gresham Height: 6-5 Weight: 261 40 time: 4.66 Short shuttle: 4.53 3-cone: 7.07 Vertical: 35" Broad jump: 9'05" 225lb bench: 20 Starts: 19 Receptions: 111 Yards: 1,629 Avg.: 14.68 TDs: 26

Rob Gronkowski, Arizona Gronkowski Height: 6-6 Weight: 258 40 time: 4.68 Short shuttle: 4.17 3-cone: 7.18 Vertical: 33.5" Broad jump: 9'11" 225lb bench: 23 reps Starts: 18

The two best receivers in the 2010 draft class have one thing in common: toughness in traffic. There are no alligator arms here – both Dez Bryant and Golden Tate will mix it up inside, jump to catch the ball in traffic and fight for that extra yard. The differences between them, however, make this particular head-to-head interesting.

Whom would you rather have on your team? Let's see what the tape says:

Dez Bryant, Oklahoma State Bryant Height: 6-2 Weight: 225 40 time: 4.58 Short shuttle: 4.48 3-cone: 7.21 Vertical: 38" Broad jump: 11'01" 225lb bench: n/a Starts: 19 Receptions: 147 Yards: 2,425 Avg.: 16.50 TDs: 29	Golden Tate, Notre Dame Tate Height: 5-10 Weight: 199 40 time: 4.42 Short shuttle: 4.34 3-cone: 7.12 Vertical: 35" Broad jump: 10'00" 225lb bench: 17 reps Starts: 22 Receptions: 157 Yards: 2,707 Avg.: 17.24 TDs: 26
Pros: Bryant plays with incredible toughness before and after the catch, no

With two weeks and a day until the 2010 NFL draft, it's a very good time for every team to be reminded just how badly a first-round bust can set a team back. If you can add yet another reason to cap on the utterly preposterous career of former Detroit Lions "general manager" Matt Millen, all the better. With the recent news that a district court has ruled that ex-Detroit receiver Charles Rogers(notes) must repay $6.1 million of the $9.1 million signing bonus he received after the Lions took him with the second pick in the 2003 draft, we are yet again brought into the world of measurables with nothing behind them.

Rogers broke his collarbone twice in his first two seasons, was suspended four games in 2005 for a third violation of the NFL's substance abuse policy, and that suspension triggered acrimony from within the Lions organization - the team said that the violation went against his contract, and they tried to recover money that Rogers would be obligated to return. It later came out

It's true in any draft -- one surprise pick can lead to the demolition of five draft boards. And from there, the toppling dominoes can lead to some very strange bedfellows. Now that the Redskins have made their annual trip to the supermarket and come away with one of the offseason's biggest prizes (and surprises) in Donovan McNabb(notes), the top of the draft becomes a bit clearer. From there, however, things could still fly off the handle with just one or two surprise picks, and the annual run on a specific position. Picks 17-32 are here; the first 16 picks can be found here.

17. San Francisco 49ers (from Carolina) -- QB Jimmy Clausen, Notre Dame: The 49ers brought in David Carr(notes) to back up Alex Smith, but the two former first overall picks haven't engendered the combined confidence you'd expect from a fringe third-rounder. Though his deep ball is overrated, and there are questions about his overall makeup, Clausen is a very accurate and efficient short-area passer, and his

1. St. Louis Rams -- QB Sam Bradford, Oklahoma: At this point, it's pretty easy to do the math. After the Rams raved about Bradford's private workout on the 29th, Marc Bulger(notes) (who is represented by Bradford's agent, Tom Condon) requested his release. The question is, what kind of offense will the Rams run with Bradford at the controls? Bradford operated primarily out of the shotgun with the Sooners, and 2009 first-round pick Jason Smith(notes) is still a better

As the NFL turns more to running back committees to stave off the effects of player overuse, specialization is key. Bell-cow backs that carry the ball 350 times a season are generally a thing of the past – in fact, only six NFL backs totaled 300 or more carries last season. Now, teams want a thunder-and-lightning combo featuring a power back inside, and a speedy threat outside and downfield.

This year, the two most impressive running backs line up on either side of that formula. While each player has the hypothetical talent to be the heart of an offense, they're more likely to be used in a rotation, with their teams playing to their best and most productive qualities. Clemson's C.J. Spiller is as exciting a playmaker as we've seen in recent years, and Ryan Mathews of Fresno State is coming up from under the radar with his own elite production:

C.J. Spiller, Clemson Spiller Height: 5-11

There are many reasons for a slide down the draft boards -- if football is a game of inches, the draft evaluation process is a game of milliseconds and millimeters. Run a 40 just out of the comfort zone, break off that route just a hair too slow on the film, fail to hit those few extra bench press reps, and the draft board becomes a very nebulous place. In two parts, we're going to establish a team of starters on each side of the ball with players who live under the radar and might blossom in the pros. (Projected draft spots, from high to low, are in parentheses - - the offensive all-sleeper team can be found here).

Defensve End: Austen Lane, Murray State (3-6) -- At 6-foot-6 and 276 pounds, Lane combines speed, size and athleticism in an intriguing package. He recorded 11 solo sacks in each of his last two seasons; of course, the question is how he'll hold up against blockers better than the ones he faced against Tennessee Tech and Lambuth. He showed potential at the Senior Bowl as a

Quarterback: Zac Robinson, Oklahoma State (4-6) -- He may have benefited from throwing to Brandon Pettigrew(notes) and Dez Bryant, but Robinson looked pretty good after Pettigrew left for the NFL and Bryant got suspended. He can run more than a bit (19 carries for 109 yards against Texas Tech in November), shows decent accuracy, and has a much better arm than the usual spread
