According to Forbes, the Dallas Cowboys remain the most valuable sports franchise for a second year in a row. The team is valued at 4.2 billion and made $700 million in 2015. With a successful 2016 season, it's assumed that number has only gone up. All but three NFL teams made the top 50. The Lions, Bengals and Bills didn't make the cut.
The New York Yankees came in second place, being valued at $3.7 billion.
