Cleveland fans earned first place by routinely packing their 73,000-seat stadium despite the dismal play of the Browns -- who have won only 36 of 112 games since 1999 -- and a climate that is among the coldest in the league.
Kansas City and Philadelphia received high marks for consistently drawing capacity crowds in both good seasons and bad. K.C. has averaged 77,300 fans per game since 1996, while Philly has filled 99.8 percent of available seats. Both figures rank second in the NFL over the 10-year span.
