I think measurables for players are important but I think people put too much emphasis on them. The NBA history is littered with players with amazing measurables but just weren't good basketball players. The Celtics had a recent player that is a prime example of this in Jordan Mickey.
Height 6'8 1/2"
Weight: 238 lbs.
Wingspan: 7' 3 1/2"
Vertical Leap: 37 1/2"
Standing Reach: 8' 10"
He had excellent lateral speed. He was an elite shot blocker. He showed in college an ability to guard the perimeter. He had a good basketball IQ. He rebounded well. Going by all this his ceiling as a PF was high. He is a bad basketball player who's game doesn't translate well to the NBA.
Now I am not saying Williams will become Mickey or wash out of the NBA. I am very hopeful that Williams will be the next Capella. He definitely has that ceiling. More realistically I can see him becoming a good NBA starter in a few years, but we will see. He very well could become another in a long line of players chosen late in the 1st round or in the 2nd round that have elite measurables but doesn't become a good basketball players and have a short NBA career.
Measurables aren't everything.
Agreed but Williams is a 2× SEC Defensive Player of the Year (2017, 2018), which is far more impressive than anything Mickey has put up, especially since Mickey had a higher BPG rate %/BPG.
You sure?
