While I don't agree with a lot of Bevell's plans, the red zone offense went from horrific to pretty good by the end of the season. On the other hand, the OL stayed pathetic all season. Bevell earned another year, Cable didn't. Hope they part ways with Cable. Anyone not named Tom Cable would be an upgrade in my opinion. But here are some others to consider -
Pat Ruel, Assistant OL, was the OL coach for Carroll at USC
Mike Solari
Chris Morgan - Falcons OL. He turned around the Falcons OL and they had a great year from D. Freeman
