I would argue that, in the playoffs he was knocking them down with regularity did you see the game in Miami where he had 40+ points. He also post up other guards time to time.
He can also:
Pass the ball at an Elite Level
Score At A HIGH clip in the playoffs
Rebound Like a 4 man
spg leader
Excellent Offensive and Defensive awareness
Great Leader
Has a RING!
I don't go by OVR ever, but if you were editing a roster like that he deserved to be 90 "Overall".
