While I don’t question the validity of John Dellapina’s story about a Rangers game in the works at Yankee Stadium—despite being a lifelong defenseman, he usually knows what he’s talking about—the official NHL stance on the matter is a tad more tempered.
According to league VP Frank Brown, the Rangers are only “among the many teams that have expressed interest aggressively” about an outdoor game for next season. He also said there’s no time frame for locking down teams or a site for the game.
Naturally, it’s in the league’s best interest to make sure everything is lined up before they announce anything official. But I wouldn’t expect that announcement to be anytime soon.
