A couple of quotes:
"To sway Rashada's decision, Hathcock and Castro-Walker offered the $13.85 million deal with $5.35 million, including a $500,000 signing bonus, to come through Hathcock's Velocity Automotive company and the rest through Gator Guard, the NIL collective that he started. Hathcock had previously committed to donating $12.6 million to the Gator Boosters, and early media reports stated the Gator Guard raised $5 million in its first 24 hours."
"Instead, a day after the $500,000 payment was due, the Gator Collective sent Rashada a termination letter of the $13.85 million deal. Still, the lawsuit claims Napier and Castro-Walker went to great lengths to convince Rashada that they would make good on the promised money even without the contract. Castro-Walker told Rashada's agents that the Gator Guard would now take on paying the deal and that "Hathcock, through the Gator Guard, would personally guarantee the $13.85 million obligation himself." The only payment allegedly made was for $150,000 to pay back John Ruiz, a prominent Miami booster, so that Rashada "could avoid possible litigation" with Ruiz who was seeking repayment from the initial $9.5 million NIL deal.
