It accomplished something...it got DA which was a cancer to the organization away from the organization. He lost the players, and there was no point in keeping him once that happened.
Crazy part was that the players actually thought that at the end of LAST season that DA was getting fired.
I agree that DA was a cancer and had lost the locker room, but if he had stayed, the defense might not have imploded, and we might have a better draft position.
