About the eFG%, I like the fact that he played efficient and hitting shots, because early in the season when there was no Trey and no Marv the team had to play almost perfet to look good but RJ(e.g. @BRK, @CHI, @TOR, vsDEN), Tinsley(just about every game) and JL3(e.g. @PHO, @BRK, vsDEN) had some bad nights during that period of time and were just not helping the core guys. They certainly didn't play perfect as well and of course I'm not denying that fact but it was impossible for the team to look good when the Veterans had Off nights. So I like to see a high eFG%!
About the USG%, actually one of RJ and Marv had to have a high USG% with Gordon out but RJ had the 3rd highest before Derrick and Enes and that is a problem for me. With Gordon out I would love to see some play action out of the post where Enes and Derrick not jus looking to score but rather making plays for their teammates, so we have an other dimension in our Playbook. But that's just me if you have a different opinion I'm cool with that.
His AST% is nice but I also didn't highlighted Garetts AST% and I also didn't highlighted any stats from Evans. It seems like you don't have a problem with those.
