PRO BASKETBALL—Detroit sat alone atop the Central Division for the first time since April 1984 after the Pistons beat Atlanta, which had led the division all season, 108-98. It was the Pistons' seventh win in eight games and 22nd in 28. Despite sandwiching losses to Utah (112-108) and Sacramento (138-113) around a 100-97 victory over the Clippers, Detroit stayed on top, thanks in part to a schedule that fed the Hawks to the Lakers and the Celtics. Atlantic Division-leading Boston, which rallied from a loss to New York with three straight wins, clinched the East coaching spot in the All-Star Game for K.C. Jones by beating the Hawks 126-106, then extended its Boston Garden winning streak against conference opponents to 55 games by downing Philadelphia 111-96. In the Midwest, Ralph Sampson had 63 rebounds and 99 points, including a season-high 33 against Cleveland, to help Houston to a 4-0 week. But the Rockets remained 4� games behind Dallas and 2 behind Utah, both 2-0 on the week. The Mavs ruined the Lakers' perfect road trip and snapped L.A.'s six-game winning streak with a 132-117 win. The Lakers had beaten New Jersey 126-115, Atlanta 112-109 and Indiana 118-108. Magic Johnson had his third triple-double of the season—29 points, 11 assists and 10 rebounds—against the Pacers.

HOCKEY—Hartford, with four wins, and Boston, 3-0, made Montreal's week unpleasant, but it was the blizzard that buried the East Coast on Thursday that nearly put the Canadiens under. After their bus got caught in snowbound traffic, the Canadiens hiked 30 minutes to Boston Garden to play their third game in four nights. Exhaustion set in—they were outscored 5-1 in the last 30 minutes—and the game ended in a 7-3 rout by the Bruins for Montreal's third loss in four nights. Hartford handed Montreal two more L's, a 5-4 on Ron Francis's overtime goal and a 3-1, and beat Quebec 3-2 and Toronto 3-0 to take over the Adams Division lead. At another snow site just 334 fans made it to the Meadowlands to watch Doug Sulliman score three goals and an assist as New Jersey beat Calgary 7-5. The Devils also upset Philadelphia 4-3 but were only in fourth place in the Patrick Division, behind the Flyers (who tied and beat Chicago 5-5 and 4-3), the Islanders and the Capitals. In the Norris Division, Minnesota stopped Buffalo 5-0 and Los Angeles 6-3 to keep a slim lead over Detroit, which won twice before ending a four-game winning streak with a 5-3 loss to St. Louis. Edmonton defeated Winnipeg 5-3, snapping the Jets' seven-game winning streak, then beat the Rangers 7-4 and Pittsburgh 4-2 for a 10-point edge on the Jets in the Smythe Division.
