Sean Payton opens up about why he left the Saints (merged)

Smallest market is Green Bay 320K, Buffalo 884K, Jacksonville and Pittsburgh at 970K, NO at 1.26 mil, Nashville at 1.3 mil and Cleveland and Cincinnati at 1.7 mill. All other teams metro area are 2 million+. They'll always want the BigEasy for pro football because its such a great destination city for the SB.
Also, the Saints are one of those franchises that have a home fanbase that spreads multiple cities. From Louisiana to probably the middle of Alabama.
You add all that up, it’s a good size market.
