Barnett certainly, Bomar was just a regular bust that was an overrated HS system guy that dropped down a level and did fine.
But Tate Martell is the King Champion of 5 Star QB busts. Let's remember he got his first offer at 14 (from Sark no less). Spends the next few years getting national write-ups before flipping his commit to aggy where he brags he'll start as a true frosh because "he's ass, my dude". Instead of placing the money where big mouth, little snot flips again to Ohio State before finally arriving on a campus as the highly touted 5 star with a Netlfix special. Rides the pine in Columbus and even tries to bigfoot Justin Fields who would transfer in and take Tate's lunch money. Little shit runs away to Miami only to then crawfish to UNLV is a desperate bid for someone to let him play. A 5 star with a 5 year career that ended with 26 completions on 35 attempts and 1 touchdown. That's elite level bust that has no equal in the game.
