NEW YORK (AP) — Luka Doncic had a game-high 30 points, Tim Hardaway Jr. chipped in 28 points against his former team, and the Dallas Mavericks beat the New York Knicks 121-100 on Saturday. Spencer Dinwiddie scored 17 points for Dallas, which outscored New York 69-41 in the second half for just its second win seven games. “I think it’s great that everyone’s in the locker room smiling,” Mavericks coach Jason Kidd said. “Everybody saw the ball go in, we shared the ball, we played the right way. ... We’re a team that lives or dies by the 3, and today we made them.” Forward Julius Randle led the Knicks with 24 points, and Immanuel Quickly chipped in 23. Leading scorer Jalen Brunson had 13 points playing against Dallas for the first time since he signed with the Knicks on July 12, but New York fell for the sixth time in its past eight games.
