Good grief, Tatum. How can you not get at least one of them to go?
Honestly, his biggest problem is that during this slump he's holding the ball soooo much longer than normal. He's making things so much harder on himself by allowing the defense to set himself.
It's obviously more than just that, with him missing some very makeable shots, as well, but being quicker with his moves would be a major plus for him.
