The New York Rangers made a huge splash last week when they acquired All-Star winger Rick Nash in a trade from the Columbus Blue Jackets, but someone forgot to tell team owner James Dolan.

Dolan, who has always been known to favor the Knicks over the Rangers, was overheard heralding Knicks GM Glen Grunwald for his acquisition of Steve Nash.

“We find it best to just let him think what he wants to think,” said an anonymous employee of Dolan’s. “It’s like his ears have a Knicks filter. Everything is about the Knicks. Eventually he’ll realize this was a hockey move, but for now, we’ll let him be.”

Dolan, who was vacationing in Turks and Caicos at the time of the Rick Nash trade, released a comment to the Daily News about the phantom Steve Nash pick-up.

“This is why we didn’t sign what’s his face, that Asian guy, I was holding out hope for Nash,” Dolan stated. “Steve is my second favorite point guard after my great friend, Isiah [Thomas], and it’s a thrill to finally get him to New York.”

Rangers President and GM Glen Sather just shrugged and laughed when he heard of his boss’s misunderstanding.

“I actually don’t think he realizes he still owns the Rangers,” Sather said while teeing off on the 14th at Beth Page Golf Course in Long Island. “We just added a perennial 30-goal scorer in his prime to a team that was a couple wins short of the Cup final. Let him think the Knicks got another 40-year-old.”

Neither Nash was available for comment.
