Unfortunately recent events don't support your opinion. 8 wins per year got the last coach fired. Mediocrity doesn't cut it anymore. The Fisher hire might work, it might not. If it doesn't, time to move on to the next coach.
Mediocrity IS a&m, and it will continue to be the norm there. Look at the revolving door of coaches there over time. Nothing has changed. More of the same to come with Fisher.
