Everyone seriously needs to shut up about "Fire RR, no results" or "Give him more time, he'll be fine", for one simple reason that everyone is overlooking:
Let me repeat that: Money. Rich Rod was penned to a multi-million dollar PER YEAR deal, for a five year contract. Mary Sue is going to be loathe to eat those last two years and the millions they entail. Secondly, the buyout. There's another couple million that the university will have effectively wasted on a two-year deal. Thirdly, the new contract: If RR was fired and Les Miles/Brian Kelly/Bill Belichick was brought in, the Athletic Department is going to have to set up a new, 5-year, multi-million dollar PER YEAR deal, that will probably have to be even greater than the one they gave RR, in order to help entice a coach into what is going to be nationally known as a coaches' nightmare here at UM if RR is fired.
Next Reason: Mary Sue Coleman
The president of the University is not an idiot, and wouldn't stake her reputation behind RR by saying "He'll get his 5 years" if she absolutely didn't mean it. Even Tommy Amaker, who we can all agree wasn't exactly an all-star coach, was given his 6 years, and then was gracefully canned for lack of performance.
For her to endorse Rich Rod, then fire him at the end of this year or next year, would reflect terribly on UM, something Mary Sue Coleman would attempt to avoid at all costs. Also, this would create a terrible hiring situation for any other great coaches we would try to lure away; no one wants to come to a program full of whiny fans and media who give their coaches two or three years and then boot them.
Regardless of what you want, or whether you're behind RR or against him, this WILL happen, and not because of any performance (or lack thereof) on the football field.
