I have not let my heart follow this closely or look into the details. Just feels like Michigan is the luckiest program in CFB and will find a way out. So my understanding of "what" took place, how many times/years it spanned, etc., is near nil.
But from what little I understand, wouldn't all the players in the two-deep be aware of this too? The one video I saw was the OSU one where the sign came in and the players all started pointing into the air. Or perhaps the cheating coach didn't tell him "why" he was calling a certain play, and that reaction isn't evidence the players are in on the scheme too.
Anyways, I ask because if ~30 players are aware of this, there's 0% chance this doesn't come full circle and fast. Kids don't keep secrets.
