DALLAS — The fans here aren’t overly enthusiastic throughout the entire game like crowds were inside the Ford Center. But this building can get awfully loud whenever the Mavs go on a run. The place erupted when Bobby Jackson had his fast-break layup blocked by Josh Howard and Jason Terry nailed a three on the other end. Whenever the crowd gets into it like that this is one of the loudest arenas in the league. Then again, they have microphones on the rims that makes you hear every shot that’s put up. So you never know what kind of tools this arena is rigged with to make it loud.
