you could have asked who is the fasted point guard in the league, and the answer would be the same........Harris...
You could make an argument for Ford, Wade, Ellis, Barbosa and Parker. Harris is definitely up there, though.
Actually Wade is a SG... if they both are PG, then i would think Wade is just stronger and better than Harris.
I don't think Wade is very fast compared to Harris, but he has a very quick first time and is very strong, allowing him to finish around the basket like few can. The fastest PGs currently out there are Ford, Robinson, Parker, Barbosa and Harris.
Vince is slow. I think Dumpy could beat him in a foot race, if they have Harris leading the way with the ball.
