Who do you have on your list?
There's a lot of guys I haven't seen/seen enough, so this isn't my definitive top three (don't have a top 5) of the top ball-handlers.
1. "Pistol" Pete Maravich
2. Allen Iverson
3. Jason Williams
Pete Maravich was flat out amazing with the ball. I've seen no one with better handles. He was also a great player which is a big reason he's number one on my list. Another big reason is he did all his crazy moves without carrying.
Iverson obviously has great handles, a great player, he also ran with the ball with blazing speed and slashed to the basket efficiently and often.
Jason Williams was like Maravich, except not a great shooter. He was streaky, but he still was a very good player so he ranks very high in the top ball-handlers list.
