I should add Noel to my list. Jawad just seemed like a good team guy. Compared to guys like Jason Capel, he seemed pretty quiet to me. Could have missed his trash talking and dirtiness, though.
As for Hansbrough, his being a jerk is more him being arrogant and having an "I'm too important for you or for this charity event" attitude. My friend said he was just full of himself. He also apparently blew off a camp volunteer who had politely asked for an autograph. Admittedly, these are second-hand stories, and hardly chronicle a long history, but it doesn't paint a glowing picture.
