I hope we get to see something like combine measurements. He's not an elite athlete, but he's not below average. He's not great at creating his own shot, but he did a pretty good job of facilitating offense this past season. He's not a ball-stopper. He's a damn good catch and shoot scorer, but he was also damn good coming off of screens and scoring on the move - I forget the exact number, but something like 95th percentile. And he plays smart, on both ends.
He hasn't been a good rebounder, but it's not from lack of energy or effort. He played with a human vacuum cleaner on the boards, and it wasn't his role. But he doesn't box any better than the rest of the Spurs roster, which annoys the living out of me.
He's NBA-ready. The problem with a lot of the "high upside" guys this year is that a lot of them have a floor of never seeing a minute in the NBA. (I disagree about some of their upsides as well, but that's another story.) I think Bey will get at least 15-20 minutes this year, pretty much anywhere he goes - except maybe for here. You never know with Pop. But he's a guy who will give a decent ROI for the pick. I don't think he'll go lower than 14, and could go as high as 8 or 9.
