There were very strong indicators during season 1 to lead one to the conclusion that Mac was not it:
1. The on-field performance the last half of the year. Not just against Bama but the lesser squads that we just barely beat.
2. His refusal to change anything on offense. I never did buy what some posters said about you not being able to change offense mid-year. Good coaches adjust. Maybe the adjustments work, but good coaches try. Trying is important, even if failing, because it sends a message.
3. If 1 and 2 didn't convince you, then the bowl game prep should. When Mac let seniors and early NFL prospects sit out practice, he treated the bowl game as an exhibition game, send the message to the team that some games are less important than others. Do you really think that Saban, Meyer, or other great coaches send that message? The crappy bowl game performance can also have an impact on recruiting, not the loss, the crappy performance.
