Isaiah Thomas used his crossover dribble to create an open 3-pointer that helped his new team build a double-digit lead in the first half. Dirk Nowitzki had a season-high 22 points, Harrison Barnes added 21 and the last-place Dallas Mavericks rallied to beat the Lakers 130-123 on Saturday night. Thomas finished with 22 points and already looks like a better fit in coach Luke Walton's offense following the deadline deal that brought him from the Cavaliers, who acquired him last summer in the trade that sent Kyrie Irving to the Celtics.
