My guess: because it is so huge it would cause death penalty talk. Michigan was stealing other teams’ practice videos.
Saban knew how to do it.

Remember when he wouldn’t allow his players to watch film or playbook over their iPads? Because they could be hacked.
Now one of Michigan’s bruhs working the project apparently spent his downtime using the same method on the same Michigan equipment to look for sexy photos of female athletes. Per the last I read, it sounded like they were going to charge him for the few creeping events while ignoring everything football.
