Some very smart posters here, like Salt and Roy, seem very bearish on Williams. Don't be fooled, I've scouted pretty well over the past decade to 12 years when I bother to watch, and I think Williams is a great pick, and attones for passing on DeAndre Jordan.
For reference, I was on record for Tatum last year, was perhaps the most vocal Kyrie trade supporter (i posted videos of IT and Kyrie showing how Kyrie was simply better, stats be [dang]ed) and after we got Morris I immediately researched and stated we won that trade.
So I feel my opinion has been overall pretty solid the past year, and I love this pick. This is not like selecting Fab Melo or Deyonta Davis, it's like picking DeAndre Jordan or Willie Caulie-Stein.
