ESPN's RPM adjusts for who you're playing with and against, who knows how well.
Their results aren't that dis-similar though:
Crowder
Horford
Johnson
Olynyk
Thomas
Smart
Jerebko
Bradley
Rozier
Green
Brown
Bradley and Johnson are the biggest surprises to me.
They have Offense and Defense split out. Thomas is by a good bit both the best offensive player and the worst defender.
