It is such a fundamental violation of the presumption of fair play that it infects everything. You already can see the game outcomes, as you document above, both winning/losing and against the spread. It also goes into player evaluation - how good are their players? On face value, pretty damn good considering the dominating results. But now, in light of this, it is a fair question - is that LB really instinctive, or is the game much easier when you know there is going to be a run and you aren't worried about being in conflict? Is that safety really well coached and disciplined when he rotates over to break up that deep shot, or is playing safety much easier when you know what is coming? We know their players can produce when they've been given the answers to the test, but if you were an NFL scout, how much emphasis do you put on production? Assessments on a player's processing speed? What do you make of McCarthy?
I'd love to see Michigan have to play a conference slate announcing their play calls to the other team. I suspect they'd be significantly worse than the usual Harbaugh years leading up to this. The obvious take away is that Harbaugh had established his level at Michigan over several years without the sign stealing. What we've seen the last 3 years represents exactly how much they've benefitted from it.
