I love when people say "move on"...it's lazy, and paves the way towards acceptance and apathy. UA in my opinion, deserves better. The only way you do better, is by analyzing the mistakes of the past. Firing Terry Bowden was a mistake. Holding on to Ianello for too long would have been a mistake...hell letting him have a second year was a mistake. We need to understand that, and we need to prevent it from happening in the future, or there won't be a UA football program worth saving.
Yes it is that obvious that he should have been kept: your University is strapped for cash, he had two years left on his contract, he had been in the history of D-1 football at UA the most successful coach, and there weren't any viable options of replacement out there. It's pretty damn clear he should have been kept. And we need to learn that lesson.
