Possibly, although I think Bayless has enough ballhandling skills to at least bring the ball up the floor in the NBA. He may never be a great passer or distributor, but at worst he could still be a good scoring-oriented point guard like Mike Bibby, or, best case, like Gilbert Arenas.
Gordon doesn't have that kind of handle, so he's a pure SG. And while he may have the athleticism to play the position and he may improve his ballhandling, right now it really limits his usefulness because you're always going to have to have a PG on the floor. He'd better score a ton of points because that kind of a lineup would get killed defensively.
And Bayless is no slouch athletically either -- 38" vertical.
