Connor Stalions, a former employee of Michigan, was charged with heading a sign-stealing ring that involved buying tickets to rival games and filming their sidelines. Even though the recording part would never work, advance scouting in person is prohibited in the NCAA but not in the NFL.
At one point, the accusations of sign-stealing threatened to ruin Michigan’s season. By the time they gained national prominence and stabilized themselves, the scandal had essentially become fodder for jokes. Once the NCAA continues its investigation, that might alter, but that seems a long way off.
