harden did the same thing tbh,
but sga has been averaging 30 for a few years now w/ great efficiency, ppl are only looking at the surface when to comes to his game
Idk he's done more for the org than anyone that came before him (in only a few years).
kd solo achievement wise is still way ahead ofc.
But In terms of impact I gotta say sga is #1 , if there is a 2nd id say Westbrook because of his longevity
