I honestly hope the best for Mac as long as it doesn't get in the way of Bama's success, but I believe his tenure at Florida has been filled with luck, bad breaks, head scratching, and excuses. I think ultimately the question moves to "how would Florida be under Mullen?"
I think Florida lacks optimism and real leadership. I think the lack of leadership predates this year because I remember Florida players interacting with fans during a game last year with a toy tiger to get back with LSU. Everyone loves to criticize Harbaugh for his antics, but his antics are off the field and out of the program. He has far more control and respect with his team than Mac. I really think Mac needs to make changes within his staff, and also find a better way to get control over his team. There is a difference between being Charlie Strong and between being Dennis Erickson in terms of control.
I think Bazza's info on fellow Florida fans is pretty telling of their expectations, and if something doesn't change then something up at the top will. I think Mac's biggest support group has been Bama fans, and that's not a good thing for Florida coaches.
