I don't think Jones and Kunc are appreciably better, they are just playing more minutes (in Jones' case taking more shots). Jones has a really nice quick hook when he is decisive and quick about his moves. Last year he was spotty with it but this year he is more consistent. He also has the benefit of Lipsey feeding him (and everyone else) the ball which has creating more easy baskets (for everyone). Kunc is almost exactly the same as he was, just playing 6 more minutes a game.
I agree with almost everything else. I would maybe go as far to say Lipsey is >> Hunter and Grill is >> than himself last year. Lipsey feels like the driver while Grill feels like the engine that makes us go. The big shots, the consistent all out effort, the massive improvement on defense...it's utterly infectious. I also agree, at least in terms of capabilities on Conditt, a guy who likely would have been a REALLY solid player had he played for a guy like TJ for 4 years. Prohm completely ruined him (and his trajectory) as a player.
