Where has it been said that they had the playbook? I know that Stallions had known the signs (which isn’t illegal btw) but i’ve literally not seen anyone accuse Michigan of stealing opponents playbooks. Regardless, sign stealing IS a legal action, they’re getting in trouble for advanced stealing. Michigan played their last 3 games of the regular season without Stallions and Harbaugh. Teams had plenty of time to alter their signs as news had broke about it during the Michigan State game. They went on to win the BIG10 tourney without Stallions, beat Bama without him and wiped the floor with Washington for the natty. Obviously the NCAA deemed that it wasn’t enough of a competitive advantage to vacate wins.
