Most the flack he got in SF was for his play calling in the red zone, they were something like 30th, 15th, 15th, 29th in his four seasons. I looked it up a few days ago. That's with a talented group and an ideal RZ back in Gore.
As I said earlier I think last nights 4th and 1 debacle brought the word "embarrassing" into the discussion and when that's coming from the big dog your time is up. He is the scapegoat in which seems to be a last minute effort to right the season. My guess is we will see more news shortly on the player front.
