Just to clarify what I'm asking... I'm looking for a former player that's excelled in the NBA.
I was going through a bunch of names... Buck Johnson, McKey, Benoit, Sprewell, Horry, McDyess, Wallace, Mo Williams, Darby Rich (just checking to see if you're paying attention) and none of them jump out at me. If we go by who has the most rings then it's Horry by a mile. That won't work as Horry has been a role player his entire career (and a damn good one at that).
McDyess was on fire with Denver and Phoenix, but injuries slowed him down... otherwise I'd go with him. Buck Johnson was a workhorse, but a role player. McKey... very similar to Horry minus the rings. It's too early to give Mo or Gerald Wallace the nod... and truth be told I doubt either can be regarded the best to play at Alabama. Benoit probably overachieved the most... making it undrafted, but he was another role player.
In the end I have to go with Sprewell. His pro career outshines his collegiate one. He averaged at least 15 PPG up until his final year in Minnesota in 2004, was a multiple time All-Star, and was part of that surprising '99 NY Knick team that somehow made it to the finals (as an 8 seed).
Note- I'm dating this back 20 years to 1986.
