They should have never let Leach go. They thought Vickers could replace him, and soon realized he wasn't the same time of fullback.... and that's how Casey was given the job out of desparation.
Hartmann doesn't get good hang time at all on his punts. It's gotten worse as the season has progressed. He has a good leg, but not much use when you don't give your coverage time to get down there.
But they still need the running game. Right now, no running game and no deep passes makes this offense nonexistant. And no, its not all on Schaub.
