And let's not forget, when Williams is in the game the team is basically playing 4 on 5. No one gets him the ball and no plays are called for him. He has shown nothing but an ability to dunk. Heck, even his screens are weak as he is always moving and doesn't set a hard screen.
Love the kid's potential but Baynes and Theis are better players and should get the minutes. Williams will get run when the other guys are hurt, and that's great. But with everyone healthy, he isn't ready to displace anyone yet. If Theis isn't back next year, and I expect he won't be, Williams will see regular minutes next year. He just needs to be a sponge and soak in the knowledge this year, little else.
And, once again, I love Williams and think he will be a stud in a couple years. But he isn't one now.
