I honestly think we need to worry about Mac quitting moreso than UF firing him. He sounds and looks like **** right now. With his 'family time' pool side picture tweet, the suicidal-sounding post game press conferences, and now the unfounded death threats allegations, it's a perfect storm for him to drum up enough sympathy from the media to help him justify a resignation.
And the pity angle will play well with all of the suspensions and injuries he'll claim he had to struggle with. All of this would overshadow his gross failings and incompetence as a head coach.
He may throw in the towel realizing that he has reached his pinnacle at UF. His two SEC East championships are the best he'll be able to do, and he knows it. Only way to go is down from here...
