It's just muddying up the discussion, which is exactly what michigan wants. The two scenarios are significantly different in that one is against the rules, and one is not. How you (or me, or anyone else) feel about coaches talking to their buddies about signs they might have observed during a game just confuses the issue. As soon as people shift over to debating about shit like whether there should be radios, or whether a good christian upstanding man should avert his eyes if he happens to see a signal going in from the opposing sideline or whether stealing signs is "part of the game" or "morally wrong" or whether or not Ryan Day is a scumbag or whatever the fuck else, that means people aren't talking about how there are clearly written rules that michigan broke many times over, and what punishments should be given for breaking those rules. Which is a discussion that michigan people would absolutely love to delay until after the season after they've ordered their national championship t-shirts.
Every game michigan plays without a punishment right now, this season, is another set of consequences they have escaped.
