No matter who or how many San Antonio Spurs were on Dirk Nowitzki, or how much they pushed, prodded or swatted at the 7-foot All-Star, he kept making big plays for the Dallas Mavericks. "He probably doesn't get enough credit for being the competitor that he is, and for being so tough-minded," teammate Lamar Odom said of Nowitzki. "There's nothing soft about Dirk. He's tough." Nowitzki scored 27 points, fought for loose balls and screamed out in exhilaration several times as the defending NBA champion Mavericks won 106-99 over the Southwest Division-leading Spurs on Saturday night for their third consecutive victory.
