But Lions couldn't run the ball most of the games. The offensive line can't block consistently and effective. And they couldn't protect consistently and effective, thus forcing hurried throws and interceptions. Kitna is not that mobile and he needs time to get the ball out. Martz is not perfect, but you have to believe that given a better offensive line he'd run more and with better protection Kitna would've been that much more effective in the red zone and in other situations.
