But then Dirk Nowitzki and his Mavericks staged a furious rally late in the fourth quarter to erase the deficit. Again.
Dallas ended Game 2 with a 22-5 run, capped off by a Nowitzki layup with just over three seconds remaining, as Dallas beat the Heat, 95-93, in Game 2 of the NBA Finals.
Just like Game 1, Thursday night's game was a close contest throughout the first three quarters. In the first game, Miami was able to rally late and pull away, and it appeared like they were going to do the same thing in Game 2.
But Dallas never quit, turned up its defensive pressure and had just enough left in the tank to hold on in the final seconds to even up the series.
But make no mistake: while it was a historic comeback for the Mavericks, it was also an epic and embarrassing collapse by the Heat.
What exactly went wrong?
