BASKETBALL—NBA: Both Milwaukee and Los Angeles suffered letdowns after their momentous meeting, with the Bucks dropping two of three and the Lakers one of three. Phoenix startled Milwaukee when Dick Van Arsdale tossed in two free throws after time ran out for a 115-114 win. Kareem Abdul-Jabbar scored only one point in the second half and fouled out for the first time this season. The next night Atlanta edged the Bucks 104-102 as Walt Bellamy scored 22 points in the first half and Lou Hudson 19 in the second. Milwaukee snapped out of its mild slump by holding Chicago to its lowest score ever, 104-77. Los Angeles defeated Detroit 123-103 as Wilt Chamberlain scored his 12,000th career field goal, and beat Philadelphia 135-121 as Wilt lifted Kevin Loughery in his arms and carried him off the court to break up a fight. But in between, the Lakers were the victims of Cincinnati Coach Bob Cousy's "most satisfying victory" when Tom Van Arsdale popped in a 15-foot jumper with one second left to edge Los Angeles 108—107. Despite the losses, Los Angeles led the Pacific Division by 13½ games over Seattle, and Milwaukee maintained a six-game bulge over Chicago in the Midwest. Boston won three in a row to open up a five-game lead in the Atlantic Division over New York, which ran its losing streak to five. "There's no reason we should be tired," said Knick Coach Red Holzman when given a chance to rationalize his club's losses, "we're just not playing well."

Second-place Indiana, five games behind the Stars, ran off three more wins after edging the Stars, beating Denver 114-99, and Memphis twice, 135-120 and 117-106. Somehow, the Pros scored a league-record 52 points in the last period of the first game and still lost by 15. New York slipped into third place in the East with four out of five wins as Rick Barry totaled 132 points and rookie John Roche 88. The Nets' 105-97 victory over Dallas broke the Chaps' five-game winning streak and the Floridians' All-Star Larry Jones, with a broken hand, was no help against the Nets, who won 110-94. By week's end, the Floridians broke their five-game losing streak, defeating Dallas 110-105 on Mack Calvin's 40 points.

New York also had a late-game letdown against Chicago when Jerry (King Kong) Korab's 63-foot slapshot slipped into the goal with less than three minutes to play to tie the Rangers 5-5. Against Buffalo the next night, New York's second line (Bill Fairbairn, Walt Tkaczuk and Gene Carr) banged in five goals to beat the Sabres 5-2.
