This post only exists because of a glaring ommission (IMO). I agree with 95% of those before me...the answer is Tinsley (pretty easy, really)...but not just for offensive/"point guard" attributes.
Someone mentioned something (sorry, 3 pages ago so can't remember exactly) about Clemente. Tinsley made kids like Clemente look less than average. No way a kid like him (or Avery Bradley, Sharron Collins, Tweety Carter, 'what's his nuts' Singletary, etc) goes off for 30 points against JT.
More than likely, a kid like that goes straight to his dorm closet, thumb in mouth, questioning his manhood, or whether he even knows how to play the game anymore after playing opposite Tinsley for 40 minutes.
He played suffocating defense, talked a ton of trash (****, he used to laugh at those he was guarding) and just plain demoralized the opposing PG, which is almost as effective as being a great PG (which JT was).
Hell, for this team, my second choice would probably be Bankhead or Cato.
