As the most valuable sports franchise in the world, it's not a surprise the Dallas Cowboys are also the most profitable by a significant margin.
Per Mike Ozanian of Forbes.com, the Cowboys lead the list for most operating income generated over a three-year period with $1.17 billion earned.
The New England Patriots rank a distant second on the list at $623 million, followed by Tottenham Hotspur at $414 million. The New York Knicks ($404 million) and Manchester United ($403 million) round out the top five and are the only other clubs that have made at least $400 million in operating income during the three-year period.
