For perspective, Alabama's bag game was run for less than $1M per year. They typically got a Saban discount to boot. That enabled them to typically be the most powerful player in the black market of buying players through family members or street agents before NIL. Sure, a team like Auburn or Tennessee would occasionally show up and go batshit crazy and buy above everyone else's head for a cycle, but Bama would still get theirs. Georgia, under Smart, wound up with a bigger budget and started to encroach on Saban's reach, but they were the only true threat for keeping an absolute competitive advantage against the rest of CFB.
The whole game was played between Bama, Clemson, Ohio State, LSU, Georgia, Ole Miss, FSU, Auburn, and few others. The game was closed and few new entrants could win their way into the dealings with the agents and such. ATM came in at the end with money ultimately so over the top that it made a mockery of the game, just as NIL was dawning in order to destroy the prior premise in general.
Now? Bama's NIL isn't dramatically higher than their prior bag budget. They don't have the alumni base or local corporate density to grow it much. They aren't even close to being relevant compared to numerous other schools, but notably Texas and Ohio State. Without Saban and his gravitas and NFL placement history, the gap just grew immediately wider. I'm not going to go into further specifics right now, but we're talking about a Grand Canyon kind of gap between where Bama is and where Texas is.
Also, if Oatis goes in the portal, much like Niblack and Bond, I expect Texas to be front and center in that recruitment.
