Recap: Like the rest of the Cardinals' offense, the offensive line started the season out with much work to be done. It allowed 23 sacks in the first eight games and then 18 after that. Relying on three veteran anchors -- Winston, Sendlein and Colledge -- head coach Bruce Arians added two young, inexperienced players to the mix in Fanaika and Sowell and by the midway point of the season they were all in sync. But that wouldn't have happened had Arizona not traded left tackle Levi Brown after Week 4 and promoted Sowell to a starting role. The Cardinals' offensive line was ranked 32nd by Pro Football Focus, but it performed better than the critics said during the final eight games. The line will get younger in 2014 with Colledge already released and second-year player Jonathan Cooper assuming the starting left guard job.
