Rich Rodriguez needs good year to save job, but how good?

Some are more patient than others, and maybe “go right” means a 6-6 record and a bowl game. That’s not exactly a lofty goal, but after bowless seasons of 3-9 and 5-7, that clearly would be improvement. Maybe going “right” means beating Notre Dame, Michigan State and Ohio State en route to a possible Big Ten championship and a BCS bowl berth.
Bottom line: Enough verbalizing in generalities. Yes, we all know Rodriguez is under pressure and this season could decide his future at Michigan. But what are the parameters that will ultimately decide that future?
