A few years ago I did some research on PF and C that went in the lottery. The averages for those players in their last year of college was somewhere around 14 points and 7 rebounds. That happens mostly because you end up with a guy like Aaron Gordon playing on a loaded Arizona team where he just doesn't score a ton of points, but he gets his boards.
I think on a KU team like the one we have, Alexander probably won't score a ton. If I told you right now that Oubre, Ellis and Selden averaged 14, 14 and 12 points, respectively, I don't think I would get too much argument. If I went further and said that whoever the starting PG is averaged 7 points a game, that's not outlandish. If I said the backup big men (Traylor and probably Mickelson) would combine to average about 11 a game, that wouldn't be a shock, either. If the backup PG and Greene combined for about 10 a night that gives you 68 points. Bill Self teams dial in the scoring between 78 and 81, which means that Alexander gets between 10 and 13. I put him on the low end of that because I actually think both Ellis and Oubre will score a bit more than I've predicted here, but 11 and 8 is roughly what Embiid did last season (11.2, 8.1). Of course, Embiid blocked more shots (roughly an extra block and a half per game, but if Alexander goes 11, 8 and 1.5, he's still a lottery pick playing on a stacked team.
