Devin Williams shot 57% FT and 41% from the field his first year
So far this year 81% FT and 60% from the floor.
The FG% will likely decline some when we start playing teams with guys able to defend him, but he's clearly worked hard to improve the weakest aspects of his game. Just with the FTs, out of 200 foul shots, his improved percentage means at least 48 more points over the season than if he had not improved (probably a good bit more in practice because making more of the front ends of 1 and 1s means more attempts).
He also looks much more comfortable with the ball down low now and I think Ahmad has shown he might be able to get him the ball better than we have the past 2 years as well. I think he could very well put up close to KJ level numbers this year. He was an 11/8 guy last year. KJ was about a 13/7 player until his senior year when he rose to almost 20/11. KJ did not get to the line as much as Devin does, so Devin might be able to improve his scoring by more than KJ did when he put it all together.
