Vujacic has a lot of potential. I suspect he just might be this generation's version of Danny Ainge. But yeah, the Lakers as a team have a tendency to be quick about expressing their displeasure and their outrage when things aren't going their way. Just like we do here at celticsblog. We do complain a lot here at the blog (but no one really listens to us, anyway), but thankfully the Celtics players and Coach generally have been dignified about the series.
Vujacic gets called for a lot of fouls because he's very aggressive on defense. It's a two-way street. If you're gonna pressure the ball constantly, and sometimes there's really no need to, then expect to get called for slapping and bumping the other guy.
In any case, he might have a point about those moving screens that Garnett was using. They could have easily been called as such. Both teams got away with violations during the series. But then again, a lot of calls that should not have happened did.
