Kaden Archie comes to mind. We kept hearing that when he became eligible he would be our best player, and that was on a team that included Bryson Williams. When he finally hit the floor, we'll, he was far from our best player.
Matt Willms was a guy that Floyd said would be an all conference and possibly NBA type player. He wasn't.
Back in the Barbee days, the gem of a recruiting class that included Randy Culpepper, Julyan Stone, Claude Britton, and Gabe McCulley. He played a total of 13 unremarkable games before being kicked off the team. He never played another game of Div 1 ball.
Going way back, we all heard rumors about how great Eddie Williams was going to be coming out of Louisiana. How he had some ridiculous vertical leap. He seemed to show a little promise early on, but fizzled out. The worst thing about it - after accepting his commitment we didn't have any scholarships left when Gary Payton wanted to play with his buddy Greg Foster, and Haskins, unlike Floyd decades later, wouldn't pull scholarships.
Rus Bradburd recruited a star big man, 6'8" Jerry Jones, from Chicago, for the recruiting class of '85. He was going to be our next great frontcourt player. Oh, and he also recruited a little guard from the same region, some guy by the name of Tim Hardaway. But Jones was supposed to be the star of that class.
