Tatum's homework this off season should be adding muscles and post game to his arsenal. I saw him switched into bigger players and he got abused. He should also be smarter with his shot selection. Mid-range game is good but should not be abused, especially when there are other better options.
His passing also need some improvement, along with his off-ball awareness on both sides of the floor. More often than not, he is caught sleeping with his assignments. Guards are also abusing him on the perimeter. He should develop better footwork on defense.
Jaylen's weakness is his shooting and handles, but he proved to be the more versatile player among the 2 J's.
