Williams played the cards close to his chest the whole process. Anyone who says "they knew" his decision is lying. He never gave a solid indication in either direction.
All that said, Williams to the NBA, will hire an agent, will go top-3, possibly #1 overall if the lottery breaks right. Sucks for next year's team, but it's a nice feather in the cap of Miller's short tenure as coach. Having a player drafted top-5 is a HUGE deal.
What sucks is, unless the policies for jersey retirement change, it's unlikely he ever gets the recognition he deserves, as the criteria wasn't met. Maybe if he's drafted #1 overall for the first time in school history he'll get the nod?
Opens up primary roles for Hill and Parrom, who each showed flashes, and minutes for Chol, who'll be a monster.
