I have been checking the stats at this site for months now as this is the only advanced stats near realtime tracker left now after 538's raptor went bust.
Wemby has significantly marched up the EPM stats table and is now ranked 24th overall in the league according to dunksandthrees and he has easily leapfrogged Sengun and Chet. If he keeps this up...he might be top 10 by the end of the year. Even more important that the Spurs accelerate their timeline to match Wemby's pace of development. Wemby needs more competent teammates to match his growth to help him win more now.
