Author Sean MacDonald visited all 32 NFL stadiums in 2013 for his "Ultimate Football Road Trip" book and has crowned the Buffalo Bills fans the drunkest in the NFL.
MacDonald is himself a Bills fan, but said the team has let the drinking in the stands grow out of control, according to Syracuse.com's Matthew Fairburn.
"Inside the stadium seemed like a free-for-all at times, with fans moving around constantly and far too many in the advanced stages of inebriation, especially in the lower level end zone seats. Beer was constantly being spilled on the concourse and stairways to the seats, making things that much more dangerous."
Despite the drunken antics of the fans, MacDonald ranked the stadium 20th overall in the league, with the St. Louis Rams' Edward Jones Dome coming in last place, and Lambeau Field, home of the Green Bay Packers, coming in first.
