Houston Texans (2009 Rank: 13th) Run Rank 3rd, Pass Rank 4th, Penalties Rank 4th How much did this line improve? Every one of them scored a positive grade and they were particularly strong with their run blocking (the unsung heroes in Arian Fosters breakout campaign). If theres a complaint its that both tackles are prone to getting beaten in pass protection. Best Player: Surprising as it may seem, Chris Myers is right up there with Mangold and Birk as one of the best run blocking centers in the league. Biggest Concern: After three years in the league, Duane Brown may be competent, but hes not good enough to deal with the top edge rushers one-on-one.
