A Canadian Sports Betting site used Google Keyword Planner to figure out which NFL team is the most HATED in the U.S. Surprisingly, it's NOT the Kansas City Chiefs. (???)
Here are the most hated teams:
1. Philadelphia Eagles: 13 states, including Alabama, California, and Texas
2. Las Vegas Raiders: 8 states including Colorado, Utah, and Missouri
3. TIE: New York Jets and Green Bay Packers: 6 states
5. TIE: Dallas Cowboys and Pittsburgh Steelers: 3 states
(You can see a map of the data here.)
