Here is a quote from Kentucky head coach Mark Stoops to Kentucky's donors / supporters after his team was stomped by Georgia 51-13: “I just encourage them to donate more because that’s what those teams are doing,” Stoops said on the show that streamed on Kentucky football’s Facebook page. “I can promise you Georgia, they bought some pretty good players. You’re allowed to these days. We could use some help. That’s what they look like, you know what I mean, when you have 85 of them. I encourage anybody that’s disgruntled to pony up some more.” Cash talks... Those envelopes stuffed with cash that were passed out after games 20+ years ago (and that could get you in trouble with the NCAA) are now the rule...
College football is more and more resembling international soccer where there is no salary cap and the rich can purchase the best talent. If fact, the college situation is even more fluid than the situation in International soccer where players do sign contracts and can be sold to other teams if under contract (or switch to a different team for free if their contract has expired). A college player can transfer entirely based in his/her own wishes/desires/NIL contract.
Some soccer leagues (e.g., the Dutch Erdevisie) act as feeders to the top-tier leagues, (e.g., English Premiere League, Spanish La Liga). They sell the contracts of their rising stars to the top leagues - earning revenue for their developmental squads. In college football, the top teams simply sign the top players from other teams on the free transfer.
