Sully, not even close.
Kid is a solid rookie who works his butt off and is already a very good rebounder.
He has an innate sense of how to use his body to create space, and is not terribly intimidated by the big names in the league.
Scoring is off-and-on right now, but it's his first year, and that's expected.
He's surrounded by some of the best mentors in the game, and is only going to improve with his energetic effort.
Green improving or being consistent? Still waiting for that, and it seems like he's had enough time to establish himself in that respect.
He's so talented and athletic, but he has gotten used to hearing that and "resting" on those laurels, and only seems to give about 75%, (at the most).
Sully? 110%, and that alone, (especially in a rookie), is worth more, IMHO.
I love this kid ... he's a Red Auerbach kind of player, and I can't wait to see how he develops as a Celtic.
