To the person that said the Cheairs brothers, you nailed it. But far and away Deaderick "Poo Poo" Cheairs takes the cake. I saw him jump off two feet just inside the free throw lane in a game and dunk it. Dude is only like 5'11". He had serious serious explosion. Quite frankly, I think he could jump as well as anyone I've ever seen and that includes Kobe and Jordan and so on. And no, I'm not joking!! If he would've taken basketball more seriously, then there's no telling how good he could've been. But athletically there was no one his equal around West Tennessee.
Now to add to that list I have already mentioned Reggie Crisp. Also I would put Marius Transou, Reggie Newbern (I think that's his name: from Southside), Marcus Hicks, Tron Sain, Kedrick Madden, Duke Chatman, and a few others whose names I can't remember.
