It looks like Sportico is doing this for the fourth time - Forbes has been doing it since at least 2012 and publishes their list in late August. Statista also looks like an August release but little information is available without a subscription. There are probably others but no doubt the Cowboys will be at the top, not just of the NFL but of all sports tems in the world.
I dont see how Atlanta is sitting at 13th with the way people love football in the South and that truly amazing new stadium they have. Top 10 in value no doubt. I also think Washington is too high, the new owners are inheriting a broken franchise with a poor stadium away from everything. The Jets are probably too high as well with the shared stadium, Bears and Texans should both be a little higher
So I guess losing like 300 games in a row propels a team like the Jets near the top of the list! Sweet! We should be near the bottom after a few Aaron Rodgers 14-3 seasons!
