Thanks for the list, but when did Mario Elie play pg? Hubert Davis, Brent Barry, and Ainge I much more consider shooting guards. Barbosa is a combo guard. Kerr is a unique case. Even more than Paxson, by the time Kerr played for the Bulls, Pippen was essentially the PG.
I'll stick with my picks of Nash and Price, because they were point guards and nothing else and they were/are multiple all-star level players who are known for scoring by the J, unlike Magic who became an acceptable shooter, but was more a scorer. Based on the stats you provide Stockton should be in the discussion as well, but I always felt more confident with Nash and Price and they appeared to have more range, but maybe I'm wrong and Stockton was as good or better a long range shooter.
