PRO BASKETBALL—The Philadelphia 76ers, despite their league-and Atlantic Division-leading 49-7 record, continued playing against lesser teams with a vengeance. In a 133-101 rout of Dallas, Philly thundered to a 73-44 halftime lead and was ahead at one point by 35. It was the 20th time this season that the 76ers had run up a double-digit lead in the first quarter and extended it in the next two. In a 116-111 win over Chicago two nights later, the Sixers uncharacteristically lacked the killer instinct, perhaps because they played most of the game without Julius Erving. Late in the second quarter Chicago's Mark Olberding poked Dr. J in the right eye, scratching his cornea. That ended his string of 321 straight games of double-figure scoring. He played in Sunday's 115-104 victory over Golden State wearing protective goggles and scored 18 points. Speaking of spectacles, the Lakers made one of themselves in a 113-104 home-court loss to Boston. Larry Bird turned the game around in the third quarter with consecutive three-pointers; conversely, the Lakers, who are best in the Pacific Division, are worst in the NBA in three-point shooting, having missed both tries against the Celtics and their last 36 in a row. L.A. has now lost all four games it's played against Boston and Philadelphia. In a meeting of Central ( Milwaukee) and Midwest ( San Antonio) leaders, the Bucks won 107-104. Milwaukee's two injured centers of attention, Dave Cowens and Bob Lanier, both saw their comebacks further delayed by discouraging medical reports.

HOCKEY—The Sutters and the Sabres gave the division leaders fits. Brian Sutter of St. Louis scored two goals and added a couple of assists in a 5-5 tie with Edmonton, tops in the Smythe. Brother Brent of the New York Islanders stole a puck from a Chicago defenseman and popped home a 15-footer to forge a 4-4 draw with the Norris pacesetters. In Buffalo, the Sabres, trailing 6-1 at 4:44 of the second, came back that period with four goals against Adams-leading Boston and went on to win 7-6. Two nights earlier, Buffalo grounded Philadelphia, No. 1 in the Patrick, 4-2 (page 28).

INDOOR SOCCER—MISL: It's a Zungul out there. That's what players from the East were saying at the league's annual All-Star game in Kansas City. Forward Steve Zungul had represented the New York Arrows of the East in all three previous All-Star games, but a Jan. 25 trade to Golden State switched his allegiances. Zungul rapped in two goals, and Kim Roentved of Wichita scored the game winner on a 30-footer at 6:18 of overtime to give the West a 6-5 win. Stan Stamenkovich of Memphis accounted for four of the East's goals and was named MVP.
