I want to see more J.R. at the end of games.
I think he is ready. I honestly think he is more disciplined than any of the Knicks that came over as far as shot selection - at least as compared to their skill level/difficulty ratio (Felton). I hope to see Ty Lawson, Aaron Afflalo, J.R., Gallo, Nene in a situation like tonight where they need to score a hoop. I like Lawson and Felton together in doses, as I know Karl will continue to dabble with - he is notorious for playing dual point guards.
I think J.R. is a good enough ball handler and passer that he qualifies as a 3rd point guard in a pinch. I also think he operates the offense closer to the free throw line than Felton or even Lawson. He is known for those long threes, but generally tries to get to the paint and has developed a underrated, and quite stellar, midrange jumper.
He's not ready to be that go to guy, and Karl might not trust him, but he and Afflalo and everyone else who steps up can fill the void as our go to scorer in those situations.
