I want John here too. He's one of the best rollmen and rebounders at his position. He's extremly efficient and has low usage. That's alot to like. There are few replacement level players available that the Hawks can even target. I think he is key to making noise in the playoffs. However, I wouldn't extend him just yet unless its for a slight discount.
I want to see him in a playoff setting and I want to see him improve in other areas. If he can come back as a decent defender, higher volume three point shooter while maintaining his accuracy, and a better ball-handler/playmaker than I would
