#5 Washington Redskins ($1.56 billion)

why ?
Skins have alot of fans on the east coast. Fans in the New England area as well as in the Carolinas from what I've heard. They also have a respectable history (3 super bowl titles, last one being in 1992, and only like 7 or 8 teams have 3 or more titles). The Skins are also the Cowboys ("Americas Team"

) biggest rivals therefore you goin get fans just based off that. And They represent the National's Capital, not that hard to figure why they have alot of fans. If the Nationals can pull off a respectable playoff run their revenue will go through the roof.
