(my olden days when I was younger)
Michael Smith....I remember going to a game and watching him hit about 10 3's in a row from out of bounds in warm ups...proof that even the worse scrubs can play ball...or at least shoot.
Mark Acres
Darren Daye
Was watching classic NBA dunk contest recently and Dina Radja was there...I used to love him...(not really random though)
More Recent:
Steve Hamer
Kris Clack
But if I had to choose one guy it would be Bryant Stith. There were some pretty random guys back then Chris Heren, Randy Brown... Back at the time I thought Stith was going to be awesome coming from Denver...
