I've felt the new Wilson and it's different texture almost fuzzy. I hate the feel of it doesn't roll off the hand.
Why on earth would they need a new ball for the NBA? The old ball was perfect.
Actually, the NBA Wilson ball from the 70's/80's had deep grooves and a little texture to the skin. Great for palming and dunking. At that same time, college used a smoother, much less grooved Spalding (best ball I ever played with once you got it broken in a little).
So in recent years, it has been a complete reversal, colleges playing the Wilson with those bulky grooves and the pros using the smoother Spalding. Probably switch again in the next decade or so.
Tatum, playing with a different body and a different ball, is struggling. Makes perfect sense. Good perimeter shooting and muscle bulk do not go well together. He's gotta play through it and let the game come to him. Focus on other ways to contribute to wins and don't force the offense. Last nite vs Miami, with him taking fewer shots, seemed to help everyone else become more involved. Less ball dominance from him and Brown will only help this offense. Keep it moving !!
