Coach isn't the problem there although he's not doing a good job. They DESPERATELY need a real offensive line and their defense is pretty weak.
They won't be firing him this year. I doubt it anyways. If they don't make playoffs (doubtful right now) AND they start off bad next year, then I can see them canning him. Changing the coach right now isn't going to change anything there. It's a player problem at the moment.
