The Mavericks had one of their best quarters of the season in the third period against Brooklyn. They outscored the home team 29-14. It was equal parts salty defense, with the Nets shooting 5-of-17 (29.4 percent), and quality offense, with the Mavericks making 12-of-21 (57.1 percent). It was good rebounding (13-6) and good bench play, with the reserves owning a 12-2 edge against the Brooklyn backups. And Deron Williams got only two shots, missing both, and suffered two of his seven turnovers. “We got stops,” said O.J. Mayo. “That’s the thing. The percentage is what’s big (for Williams). He’s going to find ways to score and keep his team close. But if you make him take tough ones all night, he’s going to make some, because he’s a great player. But if you keep him at a low percentage it gives you a chance to win.” And this came just two nights after the Mavericks scored only five points in the third quarter against Memphis, essentially throwing that game away with that abysmal 12 minutes. The end of the third quarter was particularly important. The Mavericks scored the final six points of the period to take an eight-point advantage to 77-63. Shawn Marion, who had a solid all-around game, blocked a shot that Vince Carter rebounded and fed back to Marion for a breakaway dunk just before the buzzer to snatch all the momentum for what would become a 20-point lead.
