Useful stats.
This could support my theory that the number of good drives or good quarters Mills can put together per game is heavily dependent on how much of the playbook he has learned. I think what happened in this game is DeMeco Ryans, who was faced with a must-win situation, identified the plays Kelly called the most and he shut them down. You may have noticed the 9'ers defense attacked certain plays like they knew the play was coming. Ryans also committed to covering receivers instead of blitzing. This forced Mills to go through more progressions, which is a weakness for every rookie QB.
