The Dallas Mavericks unveiled their 2011 NBA Championship banner prior to their game against the Miami Heat on Christmas Day. This is the official unveiling of that banner, which, strangely enough, features an authentic Mark Cuban signature. You could say the owner is putting his stamp on the title, quite literally.

The Heat elected to stay in the locker room as the banner was unveiled. Coach Erik Spoelstra claimed it wasn't a way to disrespect the Mavericks, but the Heat are certainly playing like they were slighted in some way. They already have a 26-point lead midway through the second quarter.
