Good topic KG, TP.
I think he's very close if he isnt in the top 20.
He's definitely a top 15 offensive player considering his assists and points, and his defense has been pretty good without him being too much of a liability for the most part.
He's the best player with highest winshares and ppg on a top 10 NBA team, so yes, IMO he is a top 20 NBA player.
He could definitely be the 3rd best player on a championship team, maybe even the 2nd best with someone like Durant as a #1 option.
