re: If allegations against Michigan prove to be true, should they receive a playoff ban?

No one knows what happened yet.

If they took pictures of playsheets with advanced cameras then had a guy telling staffers what play was being pointed at on the playsheet or they knew what certain motions led to certain plays because they had tons of info then yes.

There is an ESPN article about one of Michigan's staffers. In it says a big ten source says it's worse than the patriots and astros. That isn't being released IMO unless it's serious
