TCU knew of Michigan's sign-stealing scheme prior to CFP game, used 'dummy signals' to dupe Wolverines

You're telling me that Michigan's sign-stealing was common knowledge among Big 10 coaches, but none of them thought to use that knowledge to feed them misinformation?

I'm not sure whose incompetence is worse, Michigan's for running a sign-stealing scheme so blatant that their whole conference knew about it, or the rest of said conference for not being able to take advantage of that knowledge.
