Yea,. I'd say Miami got a bit of an edge from the refs, although I've certainly seen much worse. Still, considering that the Mavs were up late in the game, a few different calls could easily have altered the outcome.
The Heat looked more aggressive and athletic, but some of the Mavs players might also show more of those qualities if the could play that way without getting called for fouls. Chandler especially seems hampered, getting no love at all from the refs. Then there was Dirks strip called a foul, and others. There were a few calls favoring the Mavs too, but not as many.
So much for my dream of an underdog overcoming the refs to win it all in the NBA. The team that can get away with playing most aggressively always wins.
