NEW YORK — Joe Johnson snapped out of a slump with 23 points against his former team, and the Brooklyn Nets matched a season high with their third straight victory by beating the Atlanta Hawks 91-86 on Monday night. Mirza Teletovic scored 16 points and Alan Anderson added 14 starting in place of the injured Deron Williams as the Nets moved to 2-0 on four-game homestand that finishes with visits from Golden State on Wednesday and Miami on Friday. Despite yet another injury to a key player, the Nets look ready to test themselves against those powerful teams after matching their three consecutive victories from Dec. 7-12.
