I wish Williams developed a respectable jump shot, but I'm okay with him being able to stretch the defense by using his athleticism to catch gravity defying lobs. He also seems to have a great knack for making smart passes, and honestly if he can actually somehow hone his working mid range jumpshot, I don't see why he can't develop a 3 in like 4-5 years down the line, similar to Al Horford's trajectory, minus the fact Horford took quite longer.
I'm glad he's here. I know people don't think Grant Williams is our future PF, but if both the Williams can develop more defensive focus, I can see them both being our future starting frontcourt.
