We'll just disagree on this, then. Last year Russ shot a career high at the rim which is telling for a guy who attacks the basket the way he does. Shot a career high from the field on the second most shot attempts of his career...
That was in Year 12, guys posting career highs shooting the ball on high volume in Year 12 are in their prime to me. Not his peak, '20 Russ isn't the best version of Russ ever, but last year showed he was still in his prime...
I'd also argue, regarding the ramp ups last year and this year, that still being able to do that, in correlation with the aforementioned injuries that may have affected his starts to both seasons, collectively prove that he's still in his prime, albeit at the end of it...
When he starts a season free of injury and looks ass, and when he can't ramp up late in the year anymore, thats when he'll probably be squarely outside of his prime...
