They did kill the mavs. Yet there a team still hung over from a title and with ownership more concerned with 2012 FA then repeating as NBA champs. I mean Dallas still hasn't won a game as I write this.
They barely beat a Boston team without it's best wing player and best backup wing player. And the strength of the cHeat is their talent on the wing.
They beat the bobcats, arguably the least talented team in the NBA, thanks to the officials ignoring an obvious traveling call on Wade that led to the game winning basket.
Now as I write this they are down by four to the Minnesota timberwolves with two minutes to go. I expect Miami to win and be 4-0, but still I'm not impressed.
