This is a correlation vs. causation discussion. Adams is the best offensive rebounder in the NBA and it isn't close. Whitmore has played a ton with Adams. Since Amen has been starter, I'd guess Eason plays just a little more with Adams. What is most amazing is that the off court stats for Adams, Whitmore, and Eason are still higher than Kornet, Morris, and Pritchard's on court.
Completely agree that Stevo is best OREB in NBA + it's not even close. But Tari has been elite REB + near elite OREB in his own right even before playing with Stevo.
