1) I dont like coaches who talk . The Celitcs lost to 2010 Lakers and Doc runs his mouth the next season about how the Lakers "still havent beaten us at full strength" or some stupid like that.
2) If I didnt like him before, his childish MELTDOWN from that out-of-bounds call sealed the deal. Your team blew a 14 point lead in the final three minutes. One out-of-bounds call did NOT cost you the game. Your insistence on screaming "that was our damn ball...that was our damn ball" on the final two possessions might have.
Missed calls are part of the game. Its true for any sport.
