Your attempts to split hairs don't change the facts. Ball handler does not equal point guard. Parker and Vaughn are the only true point guards on the roster. Udoka, Finley and Bowen are all small forwards. Therefore, there's more depth at the small forward postion than there is at the point guard position. Pretending that shooting guards can adequately fill in running the point on an NBA team is just ignorant, and pretending that shooting guards who don't know the system can run the point for the Spurs is outright stupid.
