A roundup of the weeks Dec. 17-30

PRO BASKETBALL—As the only Western Conference team to go unbeaten last week, the Lakers ran their winning streak to seven games and their record to 22-10, five games better than that of Pacific Division runner-up Phoenix. Los Angeles's Bob McAdoo, 33, became the third active player, and the 18th ever, to score 18,000 NBA career points with 17 in a 101-97 defeat of Seattle. In another tight game, at Denver, McAdoo helped break things open with nine fourth-quarter points as L.A. surged to a 135-123 victory. The Nuggets held on to their one-game lead over Houston in the Midwest Division with a 115-108 win over Seattle in which Alex English scored 33 points and reserve guard Mike Evans had 26. Utah's Adrian Dantley averaged 34 points a game in a 2-1 week and converted two clutch baskets in the final 34 seconds as the Jazz defeated Dallas 99-97. Portland beat Golden State 106-97 to snap a seven-game losing streak—but promptly reverted to its losing ways, falling to the Rockets 108-92 and to the Spurs 141-120. In the Eastern Conference, four teams amassed perfect records last week. Among the unbeatens was Central Division-leading Milwaukee, which handled Houston 97-87, Cleveland 115-102 and Atlantic Division-leading Boston 114-98. "I think we are a team to be reckoned with," said Bucks forward Terry Cummings, who scored 23 points against the Celtics, as did teammate Paul Pressey. Milwaukee's Sidney Moncrief led both teams with 27. "We are a contender." The Bucks turned the ball over seven times to the Celtics' 17. But Boston is no pretender with its 26-6 record. Earlier in the week, it beat Phoenix 119-114, the Clippers 118-103 and San Antonio 120-112. L.A. held the Celtics' Larry Bird to 13 points—"and it didn't do us any good," said Clipper coach Jimmy Lynam. "They just have a million ways to beat you." Bird did have 13 rebounds and 13 assists in that game. Meanwhile, second-place Philadelphia hung tough, one game back. The Sixers beat Detroit 109-108, Utah 114-111 and Golden State 109-105 to give them 15 wins in their last 17 games and a 24-6 record. Against the Jazz, Julius Erving surpassed Oscar Robertson's 26,710 points to move into fifth place in career scoring. For 3-0 Washington, guard Gus Williams, the NBA's alltime steals leader with 1,423, had 37 points, 11 assists and five steals in a 125-111 drubbing of Atlanta. New Jersey capped a 4-0 week with a 110-108 win over Detroit. Guard Kelvin Ransey clinched the victory with a 15-foot jumper with four seconds left. One of the Nets' other victims was New York, which lost to New Jersey 120-114 despite a 60-point performance from league scoring leader Bernard King. "I don't derive any personal satisfaction when we lose," said King after his career-high performance. He averaged 43 points a game as the Knicks went 0-4. In the Central Division, Chicago and St. Louis were tied for second, five games back of Milwaukee.

COLLEGE FOOTBALL—In bowl games, BRIGHAM YOUNG defeated Michigan 24-17 in the Holiday Bowl; GEORGIA tied FLORIDA STATE 17-17 in the Florida Citrus Bowl; MARYLAND edged Tennessee 28-27 in the Sun Bowl; ARMY beat Michigan State 10-6 in the Cherry Bowl; IOWA trounced Texas 55-17 in the Freedom Bowl; AUBURN outplayed Arkansas 21-15 in the Liberty Bowl; OKLAHOMA STATE rallied to beat South Carolina 21-14 in the Gator Bowl; SMU beat Notre Dame 27-20 in the Aloha Bowl; and KENTUCKY squeaked by Wisconsin 20-19 in the Hall of Fame Bowl.

PRO FOOTBALL—In the NFL conference semifinals (page 12), MIAMI ripped Seattle 31-10 and PITTSBURGH upset Denver 24-17 in the AFC, and SAN FRANCISCO beat the Giants 21-10 and CHICAGO outscored Washington 23-19 in the NFC. In earlier wild-card games, the SEAHAWKS had defeated the Raiders 13-7, and the GIANTS had beaten the Rams 16-13.

COLLEGE HOCKEY—Michigan State, the Central Collegiate Hockey Association leader, shut out Michigan Tech 7-0 to win its third straight Great Lakes Invitational, in Detroit before 21,576 people, the largest crowd ever to watch a hockey game in North America. While Western Collegiate Hockey Association leader Minnesota (13-3-2) was winning two non-conference outings last week, Minnesota-Duluth swept Providence of Hockey East 9-2 and 3-2 to close within three points of the Gophers. Boston College beat Colorado College twice by the score of 7-5 to maintain its four-point lead over runner-up Boston University in Hockey East.

PRO HOCKEY—Washington shot past Philadelphia in more ways than one. The Capitals' 6-0 dumping of the Flyers moved the Caps, who got two goals from Mike Gartner, into sole possession of the Patrick Division lead. Then Doug Jarvis scored a goal with 50 seconds remaining in overtime to give Washington a 5-4 win over the Islanders and tighten its hold on first place. A subsequent 3-2 defeat of Hartford, in which the Capitals' Bryan Erickson had a pair of scores, gave Washington a two-point lead. The Isles fell eight points back with a 1-2 record last week. Buffalo's Tom Barrasso showed the form that made him both Rookie of the Year and best goalie last season. As the Sabres went 3-0 last week, Barrasso had two consecutive shutouts and 50 saves on 51 shots on goal. By beating Toronto 6-0, Winnipeg 4-0 and New Jersey 2-1, Buffalo went past Quebec and into second place in the Adams Division. Montreal ran its Adams lead to nine points with a 2-0 week during which Mario Tremblay was so hot he might have melted the ice. He scored three goals in a 7-3 stomping of the Rangers and two in a 5-3 defeat of Quebec. He got so hot—under the collar this time—against the Nordiques that he was penalized for the final six minutes after fighting. In a 6-3 win by Smythe Division-leading Edmonton over Detroit, Oiler Wayne Gretzky tied Mike Bossy and Phil Esposito for the most three-goal games in a career with 32. The 23-year-old Gretzky now holds or shares 38 NHL records. Edmonton defenseman Paul Coffey went Gretzky one better by scoring four goals in a 6-5 win over Calgary. That was the most goals scored by a defenseman in a game in two years, and Coffey scored the victory-clincher while the Oilers were shorthanded. Chicago and St. Louis continued to exchange the lead in the Norris Division; the Black Hawks were two points ahead at the end of last week, thanks to a 5-4 beating of Toronto—Chicago's Steve Larmer had a goal with two seconds left in that game—and despite' a 5-2 loss to Calgary. The Maple Leafs, winless last week and possessors of the league's worst record, fell to 6-26-5.

INDOOR SOCCER—Eastern Division pacesetter Baltimore kept a fractional lead over Chicago by beating Cleveland 8-5 and Western Division leader San Diego 6-5. The Blast displayed its versatility by getting its six goals from six different players. The Sockers beat Pittsburgh 3-2 and New York 5-4 to remain 1½ games ahead of second-place Los Angeles.
