The Dallas Mavs shut him down in the Finals 2 years ago. The Celtics series in 2010 he quit. Our team served the Celtics their worst home loss in playoff history the game before. He already had 1 foot out the door by the time that series started. He was trying to prove a point of why he was about to leave. Basically he was saying "I can't do this by myself, if I have a bad game, this is the help you have given me." First he tried the infamous LeElbow, which no one bought for a second. After that failed, he just quit in the next series, while probably thinking about buying his plane tickets to South Beach.
The guy is an absolute asshole who only cares about himself and his image. He's a great player and if he wants to come back, god bless him. But as a fan I would rather leave the asshole in south beach and try to win a ship with Mr. Irving beating LBJ in a playoff series. I mean even if we don't win the whole thing, if we could bounce his ass out of the playoffs every year that would be an accomplishment in itself.
