I think the least likely NBA player to become a coach is Jeff Van gundy. Oh wait... but on the serious side, Id say tim Duncan- too quiet of a guy lol
john ammanchi? don't know how to spell his last name, but i don't think players would take him seriously. and mutombo can coach with his voice, if avery can coach.
I'm surprised no one has mentioned Luther Head. Can you imagine what he tells the team at halftime: Coach Luther: I'm not seeing enough turnovers out of you guys! C'mon, lets see more risky, ill-advised passes to each other out there! Coach Luther: Oh yeah don't forget, this is the playoffs, so start missing your threes.
Check post #2. Stro Swift was the first name that came to my mind when I read the thread title...then I saw he was mentioned in the first post .
