NEW YORK ( TheStreet) -- Another Game Seven goes off Thursday night in the National Hockey League playoffs. The New York Rangers host the Ottawa Senators at Madison Square Garden. I am working feverishly to ensure that I am firmly planted on the couch by 4:30 p.m. PT with Molson Canadian in hand. There might not be a better time of the year than the NHL's second season. I happen to be a Toronto Maple Leafs fan. This, however, does not mean that I dislike all other Canadian franchises. In fact, when the Leafs are out of the race (every year), I root for Canadian teams. I was born in Western New York, but have always identified in many ways with Canadian culture. Right now, the Sens are the last Canadian team standing. Up until yesterday, I was preparing to root for them to win this evening. Then, I read an article by Mike Ozanian in Forbes, titled: Senators Set to Extract $300 Million from Madison Square Garden Shareholders. Mike wrote a nice article, but he did leave several things out. He estimates that every time the Rangers host a playoff game, Madison Square Garden ( MSG), the company, nets $1 million income. He extrapolates this out using the following math: If the Rangers go to the Cup they'll play at least 10 more games. MSG trades for 33 times earnings, so that would shave about $330 million worth of value from the company's market cap. That's not an exact science because Ozanian fails to factor in cost savings related to less hockey and the fact that the MSG-owned New York Knicks have already clinched a playoff spot. Postseason revenue from basketball should help offset any hockey-related losses. It's not just that MSG owns the Rangers and the Knicks and the arena the teams play in. The company also owns the stable of Madison Square Garden television networks that air the games. So, we're talking about some serious synergy between revenue streams. Ozanian points out that losing Rangers revenue because of a first round exit could hit MSG hard, particularly because the company saw net income decline by $5 million between the first six months of fiscal year 2011 and the first six months of fiscal year 2012. What Ozanian does not explain is that you can attribute this loss primarily to the labor dispute that cut the NBA season short.
