The Buffalo Bills will soon turn to the next chapter after the most recent one came to its conclusion.

As the team attempts to turn over a new leaf, the one that was… actually had a pretty good run. Despite the disappointment that will ensure this upcoming weekend by not playing in Super Bowl LV, the Bills came within one game of being there. Not many teams can say that.

But before jumping ahead to 2021, a good way to gauge where the Bills (13-3) could stand to improve this offseason can be found by reflecting back.

With that, here is Bills Wire’s final full report card for the Bills from the 2020 season:

We can draw two things immediately from Josh Allen's 2020 season. First, he laid a dud in the AFC title game and didn't get much help. And second, there is no way on earth the Bills make it that far without him. Allen finished 2020 as the NFL's No. 5 thrower with 4,544 passing yards. He barely surpassed 3,000 the year prior. Allen also had numerous other top-five statistics in his back pocket this season, including his 69.2 completion percentage which was fourth-best in the league. This is the same guy who was near 50 percent as a rookie. You couldn't have asked for more out of QB1.

Buffalo's rushing game finished 2020 as only the 19th best ground attack in the NFL. Considering Allen plays a part in there with his mobility, it potentially looks even worse for Zack Moss and Devin Singletary. But then again, there's a few outside factors to consider. Offensive coordinator Brian Daboll was not very motivated, at all, to give either guy much opportunity since he relied heavily on Allen's arm the entire year. In addition, there's the offensive line. But on a bit of a bright spot, both running backs, Singletary specifically, did show pass-catching abilities. Useful tools for Buffalo moving forward.

Stefon Diggs led the NFL in receiving yards this season with 1,535 and the next closest guy (Travis Kelce) was more than 100 yards behind him. Need we say more? Probably not, but we will. Along with Diggs, slot wideout Cole Beasley had a career-best season in Buffalo's passing attack, earning second-team All-Pro honors, and rookie Gabriel Davis had a knack for finding the end zone. The biggest downside for the wide receiver unit was John Brown. That was entirely due to his injury situation throughout the season.

Tight end: D+

The Bills got their best game out of the tight end position in the AFC Championship game, but seeing as the bar for Buffalo's offense was so low vs. the Chiefs... that's not really good. Dawson Knox highlights the tight end group for the Bills and he did not take the step forward many had hoped for. He was held to 12 games and only 24 catches and 288 receiving yards. He also is not an elite blocker. Speaking of blocker, the one plus the Bills did get from their tight ends was a surprise pair of touchdowns from Lee Smith. He had only one less than Knox. The bottom of the barrel was Tyler Kroft, who was a healthy scratch for much of the season. This position group must improve, but in their defense, the Bills might not invest much here because Allen never really seemed to favor them passing the ball. Maybe we'll see if a better playmaker can change that mindset.

Offensive line: B-

Our weekly report cards following Bills games throughout the year will essentially be a copy and paste job right here. In general, there were two positives and two negatives each week.

Positives:

• Pass protection

• Tackle play

Negatives:

• Run blocking

• Interior line play

On the outside of the Bills' O-line, Dion Dawkins and Daryl Williams were great. The latter might even be in line for a big pay day this offseason. On the inside, center Mitch Morse is overpaid, but checks out as a consistent player. At guard, players were in and out of the lineup because of injury, including Cody Ford and Jon Feliciano, and their consistency was the same. Buffalo general manager Brandon Beane said he wants his team's rushing attack to improve in 2021... and the offensive line is a good place to start that operation. Basing still off of what the O-line was asked to do, pass protection was used more often than run blocking, so these guys still weigh out above an average grade.

Defensive line: C+

A big reason for Buffalo's early-season struggles against the run was their play in the trenches and naturally the front-seven overall. The Bills added Mario Addison on the edge via free agency last offseason and he was inconsistent. At least across from him Jerry Hughes still was. Not having Star Lotulelei appeared to throw a wrench in the middle of the defensive line, which might be the overwhelming reason for Buffalo's struggles in the trenches on defense in 2020. No one from Harrison Phillips to Vernon Butler to Quinton Jefferson could ever really fully fill his shoes. Getting Lotulelei back in 2021 and another guy who is good at that same blocker-eating job should be a focal point for Buffalo's upcoming offseason. Worth noting, Ed Oliver got rave reviews from both Beane and head coach Sean McDermott at the end of the season.

Linebacker: C-

Tremaine Edmunds and Matt Milano played various parts of the season dinged up with a slew of injuries. That played a big part it the down year both had. Despite turning things around a bit later on in the year, it was still and overwhelmingly bad campaign from this position group for the Bills in a sense of... the damage was done. Along with their top-two guys, the Bills got hot-and-cold types of performances from AJ Klein. At times he was the Defensive Player of the Week, at others, he was a turnstile.

Secondary: B

The Bills secondary, like the rest of Buffalo's own defense and units across the league, got off to a rough start. For the most part, the players the team was expected to rely on, cornerback Tre'Davious White and safeties Micah Hyde and Jordan Poyer did well. At slot cornerback, Taron Johnson got off to a brutal start while things never really settled down at the No. 2 spot between Levi Wallace and Josh Norman. In what seems like a yearly tradition for McDermott, expect additions to this group ahead of next season.

Special teams: B+

Since we're taking the entire 2020 season into consideration, the Bills had a mostly good campaign on special teams. However, rookie Tyler Bass got off to a slow start, but eventually turned it around. By the end of the year, he made 50-plus yard kicks in the postseason look pretty easy. Punter Corey Bojorquez had some clamoring he should've been a Pro Bowler while the rest of the Bills' special teams, including the return game with Andre Roberts and coverage units were all above average. Coordinator Heath Farwell has a good thing going here.
