He ended up at Arizona State.
I don't think we'll ever know what fully happened but as far as I know, he signed a deal with Miami, but then his people took that deal to a UF booster to see if it could be bettered. In the end, they came to the UF collective with the "deal" already in place and funded and he flipped to Florida about a month before signing day.
But then it started to fall apart. Some of the NIL was straight up against NCAA rules and possibly illegal in Florida.
There were rumors that Miami had already given him money and now UF was expected to pay Miami on top of the deal as well as some unlisted legal fees that were being added to the top.
But the contract also apparently gave UF the right to end the deal at any time without penalty.
The deal couldn't be salvaged and the booster that had agreed to the deal walked; the Gator Collective that was the one that agreed to the bad deal was acquired by a different Gator Collective.
There were some rumors that Ruiz in Miami knew it was a bad deal and did it anyway to poison the well if someone else got him. Of course, if you follow Ruiz, there's a decent chance that all of his contracts questionably legal and funded. His company is about to be delisted from NASDAQ for fraud.
