Yeah but most lefties are and they're wildly good at creating space or getting a good angle to get their shots off with their left no matter what. Harden, Ginobili, Van Exel, D'Angelo Russell, Isaiah Thomas (the younger one) etc. Righties, for whatever reason, can't do that like lefties
Difference with Zeb and THill is Zeb can actually take his man off the dribble with his right. He can't make a right handed layup to save his life, but at least he can put himself in a position to score with his off hand. I haven't seen that from THill yet
