Yes you can't compare year 3 Stanford versus year 3 Michigan. Stanford had better, more experienced players because of the previous coaching regime. RR was left with horrible young depth when Carr left. RR did more with less than Harbaugh. Your belief that Harbaugh did a better coaching job is wrong. It is objectively wrong. So yes you have a point that you can't compare the two situations.
