I would say Webster still has more big game experience than Biggs does. Olympic qualifier>Juco
You have to remember that Parker was the only scholarship point guard on the team last year, and he was barely even getting playing time by the end of the season. I think Biggs and Webster can provide a lot more than Parker.
I think you are pretty limited when you are 5'9, an average ball handler, average shooter, and an average athlete.
