Detroit Lions roster review: Center

As part of our season wrap-up series, we are going to examine how each player on the roster performed in 2014. Next, let's take a look at the Detroit Lions' centers. (Note: Stats are from regular-season games only, and numbers for sacks, QB hits and QB hurries allowed are from Pro Football Focus.)

Dominic Raiola - 15 games (15 starts) | Allowed 4 sacks, 2 QB hits, 17 QB hurries

The Lions' decision to not re-sign Raiola should come as no surprise considering he finished the 2014 regular season with a -17.2 grade on PFF. He was quite bad for most of the season, and he obviously didn't do the Lions any favors by getting himself suspended for their Week 17 trip to Lambeau Field. Raiola may have had a bounce-back year in 2013, but 2014 was the exact opposite. He took a major step back, and he's no longer in the Lions' future plans as a result.

Travis Swanson - 16 games (5 starts) | Allowed 1 sack, 3 QB hits, 11 QB hurries

Swanson didn't fare very well when he was forced to step in as the Lions' starting right guard, but he was quite good as their starting center in Week 17. It's extremely good news that Swanson didn't look out of place as the starting center considering he is slated to take over that spot on a permanent basis next season.
