I still had KqWin on ignore, and I'm catching up. What's the question here? GG's talent is creating separation for a guy who's 6'9" / 220 lbs and decently athletic. He's able to create looks for himself. There's value in that. How many of those shots he makes matters, but it's hard to draw conclusions about how well he'll make shots 3 years from now.
In the end, the question is whether he can be a high-level scorer at the NBA level. We won't know this based on Summer League or even the G-league. He's got the skills to do it though. He's also a guy I think who wants to be good.
Now that we're no longer having violent pre-draft debates, I'll take guys off ignore.
