I don't think anyone has ever denied his attitude issues. I'd certainly challenge the notion that he was hurting us more than helping, and I'd probably argue against TBL 'giving up' on him as they traded for assets to go in a different direction (I don't think we 'gave up' on Buch, we made a hockey trade) to go in a different direction).
My issues at the time (and I guess still now)
- the team/franchise was so inept that they didn't have anyone available to them to help Miller with his attitude issues. And this includes such 'leaders' as Hank, Kreider, Stepan, Nash, Staal, Girardi and of course McD
- that having decided that they simply couldn't deal with the immense attitude problem, the team basically gave away a 24 year old, 50+ scorer, for free
