Tatum to me has all of the talent in the world. He can get pretty much any shot he wants, when he wants. The problem is he can't finish. He cannot put the ball in the hole. It's part shot select, part fishing for calls, part being too skinny, etc. You cannot/should not sell low on a player who can get his own shot whenever he wants in this league, even if he is inefficient for the time being.
I remember Kemba being a really inefficient player when he first came into the league, but by about the 5th season he had finally put it all together. Tatum right now is not the player i want him to be but i'm willing to be patient. I was wrong about Marcus Smart developing into something so i'm willing to be patient with Tatum.
