While that's definitely not why he was sent down there, I believe a big missing from his game was his shot, so it's good for him to be developing his scoring potential because I really do believe he has the ball handling and defensive skills to be a solid PG in the league.
He definitely has the physical tools. We basically have not had a PG who had a well rounded game since Porter and Strickland were here. Every PG we have had since then has had holes in their game except for when Scottie Pippen was playing out of position.
