Somewhere in their travels to the four corners of the globe during the NHL's all-star break, maybe the Winnipeg Jets will find a duty-free goals store or possibly a website that deals in softer hands or foolproof offensive finish. Those items were conspicuous by their absence this week when the Jets made a brief, two-game pit stop in the east. One goal for two nights added up to a pair of losses, the latest a 3-0 blanking from the New York Rangers in Madison Square Garden on Tuesday night. It was Winnipeg's third loss in a row, and third in three tries this season against the Eastern Conference-leading Rangers. It duplicated the result here on Nov. 6.
