If it's true that Lucas signed a big NIL deal:
1) A) Assumption 1: It's my understanding that NIL deals are not actually between the University and the player, but are actually between a non-university organization, like a booster club; therefore, the University is not a party to the contract.
B) Assumption 2: It's my understanding that the University cannot be formally written into the NIL contract as a 3d party beneficiary.
C) if I'm correct on my assumptions, I don't think UW has any rights against Lucas, and I don't think Lucas has any obligations to UW. UW is going to get whacked.
2) Whoever gave Lucas the NIL deal may have express - Lucas gets the NIL money while he's playing for the Badgers is written into the NIL contract - or implied - it was implied that Lucas only got NIL money while playing for the Badgers - rights against Lucas that may allow the NIL giver to recoup some of its NIL money. But, I doubt the NIL contract can be used to prevent or delay Lucas transfer.
If the NIL contract does not protect the NIL giver, they should sue their attorney who drafted the NIL contract. (I'm available for your next dumbass deal with a kid, see below for my retainer)
3) This looks horrible and will hurt recruiting.
I think most would understand that if a NIL Deal maker gave Lucas an NIL deal to play 4 years at Wisconsin that Lucas should not receive the final 75% if he leaves after 1 year. (Holy Cow, if anybody gave a young kid Big Money in one lump sum, they should be able to recoup 75% - BUT, they are too stupid to live. If you know anybody who did this, please have them call me, my retainer will only be enough to buy all the swampland in FL.)
4) Again, Wisconsin is playing the portal worse than it plays football
