KD explains why he made the decision that he did. The problem is you're looking at it from a fan's perspective. I agree, as a fan, I hated the decision, just like I hated lebron joining up with wade and bosh. But look at it from KD's perspective. His goal is to win a championship, why wouldn't he put himself in the best possible situation?
So I have no problem with you hating the decision he made, but to call it pathetic is just ignorant.
