Agree mostly with your points, well said.
I think for some, his two years were filled with promise/potential and in 21 years of watching the Huskies, I ever have witnessed such a mentally weak player who gets down on himself so quickly and makes so many mental mistakes. I can unequivocally say, he's the most frustrating Husky I ever remember. So maybe others feel more free that he has moved on to just unload how frustrating his potential that was never realized because of his mental weakness and poor shooting. Further, fans were expecting a junior year DHam to put it together more and finally fulfill some of that promise that we would catch glimpses of from time to time.
The other thing is if that quote is accurate, it really is incendiary as he was super versatile yes, but really has no business putting himself above the greats like Donyell, Ray Allen, Caron, Emeka, Kemba, Shabazz et al.
I wish DHam the best, but KO knows the NBA and he went against him on this. I didn't begrudge Andre or Rudy or anyone over the years re: early entry.
