The Big Ticket knows how to hold a grudge.

Midway through Ray Allen's first game with the Miami Heat, he shook the hand of some Celtics coaches and even gave Kevin Garnett some dap. Garnett was less than pleased.

Okay Kevin, we don't really understand why you feel betrayed that Ray Allen left a team he played less than a third of his NBA career for, but you're certainly entitled to that position. But at least give Ray a half-hearted fist bump or a slight nod or something.
