Someone has to block, the O-line sure wasn't last year. The game definately changes when you have a Carson Palmer manning it instead of Ryan Fitzpatrick. Just like the running game opens up the passing game, the passing game opens up the running game. Take one of them away, and you aren't going anywhere. The lack of a passing game sure took its toll on the offense last year. Thats one reason I'm definately optomistic that this year's team getting back into the playoff hunt.
