As long as Texas A&M, Miami, Texas, and any other program that believes its their birthright to win a title, they'll always be a team that will back up the Brinks
Even that has its limits. I can tell you there isn't infinite NIL money to be handed out at Texas. A lot of the big money people don't even contribute to NIL because they don't believe in it on principle. A lot of those guys are old money and have straight up told the AD no when it comes to donating to NIL. Texas is doing work elsewhere with the not so big money and also leaning on the alumni/fanbase for donations but are far and away from having anything sustainable on a yearly basis. People also have to remember it ain't just the football team looking to get paid.
Also look at A&M for an example. They went all in on that '22 class with under the table money(not NIL), didn't set up any kind of NIL structure and then ended up with a class out of the top 10 in '23, then basically had to empty the well to retain talent from the '22 class so they weren't even much of a player during transfer season and they are short like 15 scholarship players.
So all in all these schools are not swimming in NIL money, for major players you'll have corporate NIL step in and help out but those are mostly reserved for players like Bijan.
Lastly there is no way that kid was offered 13 million. I could believe a number around 3 million spread over 3-4 years but 13 is an absurd amount.
