The Badgers & Lucas signed an NIL deal which isn't, yet, legal. UW did not enter Lucas into the portal based on this non-legal document. Imho, the transfer portal system will be swiftly dying, as its structure and "rules" are very imperfect. Lucas supposedly wanted to be closer to home, was denied the "standard" portal procedure, so unenrolled from UW & enrolled at Miami. I'm sure there was contact with members of Miami football, as Lucas is a football player, so not sure how tampering gets proven.
What I say about this comes from information I have from a source that's usually right. Someone who knows a quite a bit about how some schools have been operating within the system and outside. He also knows people in the Miami consortium, and at the University of Miami. Here's what he has told me about what happened. Is he right? Believe what you want. I think he's on the money with it for reasons I can't divulge.
Lucas signed an NIL deal, but it hadn't kicked in yet. He's a Florida boy and someone he knows was talking to someone close to the Miami program, and they said they'd really like to get Lucas at Miami, if he was available. So, the word goes out to the deep pocket alumni, and they come up with a package of NIL money that Lucas can't refuse. So, he figures he'll just enter the portal, and Wisconsin can suck it up because the contract he signed hasn't kicked in yet. Apparently, his agent at least suggested that was okay or said that Wisconsin would just let him go.
The problem is, someone found out that the money was offered as an "incentive" to leave Wisconsin for Miami and wasn't a question of Lucas wanting to leave and submitting to the portal before fielding offers. He was "induced" to leave by the offer of several times the amount of NIL money he had from the Wisconsin consortium.
Let's look at Wisconsin's position in this. They obviously have some documentation or hard evidence that Lucas was given an offer before entering the portal. In fact, it could come from players on the Badger team. Guys he thought would keep his secret and haven't. Additionally, they must be pretty much aware of the timeline of communications between someone representing getting him and/or his agent, to pull the plug at Wisconsin. There has to be enough data for them to even consider the lawsuit against Lucas and whomever else is involved.
There's no way that the University of Wisconsin would even embark on this journey if it was just a fishing expedition. They have a smoking gun, or they would have let the kid go.
Anyhow. Make your own decisions.
