Injuries are one thing, but these coordinators have no creativity.

It's both, no takent and KK isn't good. The offense was terrible before the bottom fell out and the starters on offense were still playing. I'm sorry but McCoy being injured should not have been such a huge factor. He is at most a 2 point differential player.
McCoy being injured is a huge factor. It is for any team when your center is your best O-lineman.
