I'm not sure why this is funny as this is the only real weakness on the Golden State team. And with the spacing he will get, I hope this comes to fruition. Steph is just too small and not athletic enough to shoot over defenders in a midrange halfcourt situation.
Klay is but he isn't available right now.
Wiseman size and athleticism will cancel out situations that just happened vs Memphis.
He should routinely get single coverage and should be a top option to rely on in a slowed down defensive battle.
All of this is assuming Wiseman takes the necessary defensive step to be on the floor in crunch time situations.
