I agree with your assessment that Williams will be in the 7-8 PPG range, which is just fine as long as he gets us into our offense and doesn't turn the ball over.
I do think it's possible though that he develops his game this summer and becomes a 12 PPG scorer. With the lack of PGs there is a good chance he is either 1st or 2nd on the team in minutes played. He has a solid mid range game and with his size should be able to get his shot when he pleases over smaller defenders. He's also looks to be pretty good in transition. If his three develops, look out.
I chose Uhl, because I figured it was a safe bet given what we've seen. With the lack of big time minutes played by anyone outside of Jok, this is pretty much a guessing game at this point.
How do you know this?
