Believe or not, the Dallas Mavericks are getting it done with some defense.  In their last 10 games, opponents have all scored under 100 points.  With their winning streak they have tied themselves for the Southwest division and Western Conference lead. Last night’s game versus the Grizzlies they were able to sneak out a victory by Dirk Nowitzki getting a superstar call and went to the line to put them up by one.  Mike Miller of the Grizzlies could have won the game at the buzzer but his lay-up shot missed when he lost the handle of the ball for a split second.  Owner Mark Cuban definitely has been a happy camper lately.
