Thanks for the link. Can you give us a quick and dirty on where they're coming from? Are they stat based, or do they prefer certain types over others? I'm not sure what's quite getting two players I've never heard of to have higher rankings than both gunner types (Ace, Trey, Fears(?)) and 3 & D types (Coward, Powell)
There is an "about this projection" section on the site. That will give more detail than I can. Generally, stat only models (which this appears to be) prefer players with a wide range of indicators even if those indicators don't seem important for their role like rebounds for guards or assists for big men. Some key indicators shared by most models are steals, ast/tov, and 2FG%. Some indicators that don't seem to have great value are USG, raw PPG, raw 3FG%. Every model is different, but those things tend to be shared across stat focused models.
