Lets see where our young boys rank for their position:
D'Angelo Russell ranks 15th overall among PGs with an overall RPM of +1.43. Offense he's +3.11, Defense he's -1.68. Offensively among PGs, he ranks #7.
Caris LeVert ranks 20th overall among SGs with +0.23. Offensively 1.49 and Defensively -1.26. LeVert offensively ranks 13th overall among SGs.
Jarrett Allen ranks 8th Overall among centers with +2.40. On Offense he is +0.59 on defense he is +1.81, which places him at #17 defensively.
Spencer Dinwiddie ranks 29th among PGs with an overall of -0.23 He's +2.42 on offense and -2.65 on defense. Maybe now people will stop complaining about Russell's defense? Spencer ranks 14th among PGs on offense.
And although he isn't young at age 27th, Joe Harris ranks #9 overall among SFs with +2.35. Defensively he's -0.87 and on Offense he's +1.48 (6th best overall)
Ed Davis, who is listed as a PF for some reason, clocks in at 17th overall with a +1.19. Offense: -1.04 Defense: +2.23
This pretty much matches the eyeball test. These guys have been solid for us so far this season
Jared Dudley, The Floor Space King, actually is in the positive with a +0.29 (-0.97 offense, +1.26 defense). Got to give the dude his props here

Everyone else as you can imagine, is in the negative:
Kurucs overall is -1.21 (offense -0.29 defense -1.50)
Rondae overall is -2.62 (offense -1.77 defense -0.85). This season is really off to a disastrous start for him.
Allen Crabbe ranks 99 out of 99 players listed at SG with -4.20 overall (offense -2.95, defense -1.25)
