How do you feel about Rondo & KG leaving before the buzzer?

With time still on the clock, Rajon Rondo and Kevin Garnett are seen leaving the court angrily at the end of Game 7 of the Eastern Conference Finals against the Heat. The 1991 Detroit Pistons were ridiculed for a similar act, though more egregious as they all walked out as a team and the game had to be stopped. LeBron James got lots of flack after the 2009 Eastern Conference Finals for leaving the court without giving any handshakes to Magic players. There is no set basketball code of ethics when it comes to behavior following a brutal playoff series. This isn't the NHL playoffs. Nonetheless, if the 1991 Detroit Pistons and a 2009 LeBron James got crushed in the media for their actions, then so should Rajon Rondo and Kevin Garnett.

Can't say I was surprised. If you had asked me to predict which two Celtics players wouldn't shake the Heat players' hands I would have immediately guessed Rajon Rondo and Kevin Garnett. I don't think the whole shaking someone's hand thing is that big a deal, but I do think it's the classy thing to do.

What are your thoughts? Do you feel Rondo and KG were immature and poor sports or do you think they did the right thing? If the Celtics had won and it was LeBron and Wade that left, while all the other Heat players congratulated the C's, what would you say about them?
