I do think there is probably more here.I don’t think it’s a huge stretch. The collective could argue for specific performance. Do I think they’d win? No, but I wouldn’t want to do anything until it got sorted.
And I think there’s probably got to be something more here, but if not I still probably wouldn’t say Wisconsin was in the wrong. If the rumors are true, he screwed Wisconsin over and he’s being screwed over in return.
However:
I think its a stretch around the world to think a school's collective would sue the school they support for a million reasons. Counterproductive, bad PR, etc.
If Wisconsin paid the guy early (almost certainly to get the money out before the House rev-share cap is in place) that's the risk they took. The contract should have had some clawbacks or some other non-performance based protection built in (e.g., sign autographs in Madison on Tuesdays during the season).
This isn't kindergarten, two wrongs don't make a right. The NCAA rules are pretty clear if the paperwork is submitted the player must be in the portal within two business days. And the courts have affirmed multiple times schools/NCAA can't restrict player transfer. It's so black and white that's why I think there's something else to the story.
