Justin Rogers' final Lions grades: Offense / specialists

QB Matthew Stafford - Through three-quarters of the season, Stafford was a legitimate MVP candidate, completing 67.7 percent of his passes for 21 scores and five picks. But a broken finger led to a late fade. GRADE: B+

T Taylor Decker - The rookie played every snap at left tackle and showed steady improvement after some early struggles. His 4.5 sacks allowed and six penalties mirror Riley Reiff’s 2015 figures. GRADE: B+

G/C Graham Glasgow - The third-round pick wasn’t as steady as Decker, but provided needed position flexibility when the Lions needed him. He did give up too many sacks (3.5) for an interior lineman. GRADE: C+

C Travis Swanson - Before his season ended prematurely with a concussion, Swanson was arguably the Lions’ most consistent lineman, showing significant improvement as a run blocker and pass protector. GRADE: B+

G Larry Warford - Warford continued the steady play the Lions have grown accustomed to during his four seasons manning right guard. He allowed three sacks, but had no holding calls all year. GRADE: B+

T Riley Reiff - Reiff was a significant upgrade at right tackle, but gave up more pass-rush pressure than you’d like to see from that spot. GRADE: C

G Laken Tomlinson - Players are expected to make their biggest jump between years one and two, but Tomlinson was yanked from the starting lineup early in the season. He closed the year playing better, offering a glimmer of hope. GRADE: D-

T Corey Robinson - Robinson filled in for an injured Reiff twice, holding his own and offering the Lions an option if they lose the veteran in free agency. Robinson also handled blocking tight end assignments well. GRADE: C+

RB Theo Riddick - Riddick made strides as a ball carrier and was an even bigger factor in the passing game than 2015. Injuries (high ankle sprain and wrist) hampered what would have been a monster year. GRADE: B+

RB Dwayne Washington - No one is doubting the rookie’s skill set, but his patience and vision left plenty to be desired. He averaged 2.9 yards per attempt with only three of his 90 carries going for more than 10 yards. GRADE: D

RB Zach Zenner - After a slow start to the year, Zenner found a groove late, suggesting he deserves a bigger role in 2017. The biggest thing will be cutting negative runs — 16 percent of his carries were stopped for a loss or no gain. GRADE: C+

WR Marvin Jones - Jones started off hot, leading the NFL in receiving and big plays after five weeks. But down the stretch, he wasn’t a factor more often than not. His career-high six drops were also troubling. GRADE: B-

WR Golden Tate - Tate had the opposite season of Jones, starting slow and finishing strong, leading the team in receptions (91) and yardage (1,077). He showed more versatility with his routes and backfield usage. GRADE: B+

WR Anquan Boldin - Boldin put some early-season drop issues behind him in the second half and finished with 67 grabs for 584 yards and a team-high eight touchdowns. He was a key weapon on third down and in the red zone. GRADE: B+

WR Andre Roberts - As the fourth receiver, Roberts’ opportunities were limited, but he had two long catches to key comeback wins. As a punt returner, his 12.3-yard average was third and he was one of two with two touchdowns. GRADE: B

TE Eric Ebron - Ebron’s per game production continues to improve and he’s making more big plays, but blocking and drops continue to be concerns. He put seven passes on the ground during the regular season and two more in the playoffs. GRADE: C+

TE Matthew Mulligan - Mulligan did what he was paid to do. He isn’t going to catch many passes, and shouldn’t be based on the fourth down against Seattle, but he’s a fundamentally sound blocker. GRADE: C

K Matt Prater - Prater set a career-high with 31 field goals, including a perfect 7-of-7 on kicks from 50 yards or longer. He also maintained his perfect mark in the clutch. GRADE: A-
