That's interesting. I just checked the 2014 version of the Forbes list right here:

50 Most Valuable Sports Franchises - 2014

The Yankees are #4 at $2.5 billion, and the Cowboys are #5 at $2.3 billion. Here's the money quote:

The Yankees are the most valuable non-soccer team in the world with a worth of $2.5 billion.

The article doesn't specify what is included in a team's balance sheet when it assesses its value. Maybe they leave the stadiums out of the calculations for this list?

That was July. The Cowboys have surpassed the Yankees.

For the eighth consecutive year the Dallas Cowboys, worth $3.2 billion, are the league’s most valuable team. The only sports team worth more is Real Madrid, valued at $3.4 billion,

1. Real Madrid - $3.4 billion
