Jaren Jackson, 4th on SPI, 12th on EPM, 38th on BPM. BPM tough on those with low assist rates.
Aaron Gordon, 18th on SPI, 13th on EPM, 49th on BPM. BPM again further from other 2.
Derrick White 23rd on SPI, 38th on EPM, 69th on BPM.
Looney, 41st in SPI, 114 on EPM, 71 on BPM. Finally a middle value for BPM.
Huerter, 59th on SPI, 107 on EPM, 139 on BPM. SPI the outlier on this one.
Would need to check more to find or claim a pattern. (Not going to do it at least now.) Someone can compute the master correlation grid again
and / or search for best fit for a metric blend, retrospectively for this season or try for a relatively close predictive blend.
