You are correct, but as much as that part of his game has improved, he still needs to come up with at least one more shot in his repertoire, like possibly a 10 foot jump shot
Spot on. If Zion a) stays healthy and b) develops a mid range jump shot, he'll be unguardable. The only question in my mind is if he has the competitive drive to work on his game and his body and become a true star.
