The NHL is working with the Yankees' high command and representatives of the city to try to play a game at Yankee Stadium next winter. While there are plenty of logistical hurdles to clear, the principals are interested. "We'd love to do it," said Rangers' GM Glen Sather, who is always up for a new hockey adventure. Obviously, the NHL feels the same way. The Yankees might figure to be a bit hesitant about having the final pro sporting event at the old Stadium be a hockey game. But sources familiar with the discussions insist that the Bombers' brass is into it, with COO Lonn Trost serving as the Yankees' point man in discussions with the NHL. The league has gotten rave reviews for its outdoor-game movement, especially with this season's New Year's Day contest in Buffalo that was played in the snow in front of more than 70,000 fans. The Islanders have made it clear that they want in as well, sending front-office delegations to meet with Trost and Yankee Stadium personnel no fewer than half-a-dozen times over the last 18 months.
