There should probably be a cut off on height - like it should definitely be under 6 ft and maybe even 5'10" or under. A 6'1" pg is not undersized.
The reason that guys like Webb, Bogues, and Boykins get mentioned so often is because they were so short, yet still effective. Put me down for AI because he wasn't really anywhere close to 6 feet, but was still able to completely take over game after game.
