That is the reported budget. UGA pales in comparison to the Boosters Budget. The day after NIL is announced Saban goes public with Young's almost $1M NIL deal. Deal was done well ahead of that so you can see the amount of money coming from their Boosters.
I don't have time to research every company's ties to Alabama, but Bryce Young has sponsorship deals with Cash App, Leaf, Onyx, Studio Wildcard, and Logan's Roadhouse, to name just a few. These are national brands, and it seems unlikely they are jyst throwing booster money at Alabama's QB.
Young is represented by CAA talent agency, so most of his deals are probably legit endorsement deals.
