Sims is having his usual quiet season, in which he plays pretty well but doesn’t wow anyone. He might be one of the least talked-about players on the entire team, which is usually a good sign for an interior lineman.

Having said that, Pro Football Focus has him rated as the Lions’ worst interior lineman at -1.3 overall, and second-worst offensive lineman behind only Corey Hilliard, thanks to a -7.1 rating in run blocking. He’s actually above-average in every other area, and hasn’t taken a penalty all season, but the atrocious run-blocking grade brings him down. The Lions are 1-3 in games PFF has him graded worse than -1 in run blocking.

Grade: B-


Sims hasn’t made a huge impact in either a good or bad way, which has pretty much been his mantra since he arrived in Detroit. He has, however, avoided flags and consistently played every offensive snap this season. He also had his best game of the season against Dallas, so maybe better things are ahead.

Grade: B

Vs. Expectations

Sims is doing exactly what he’s supposed to. He’s a consistent veteran leader who plays every snap and doesn’t give anybody a headache. He’s not a bulldozer, but he’s fundamentally sound and rarely lets up pressure on the quarterback. He’s neither better nor worse than expected.

Grade: C


Sims has always been one of the Lions’ most stable and reliable linemen, but now he also looks like the least talented. Still, he’s earning his contract and should still be around through the end of it in 2014.

Grade: B-
