The Dallas Cowboys are riding a high, fresh off their win over the Seattle Seahawks to improve to 5-1. It’s the first time the team has reached a high at this level in several seasons.

So why isn’t the team even more popular?

Dubbed “America’s Team” for years, the Cowboys actually are only America’s fourth-most popular team according to a new Harris Poll conducted in mid-September.

The top dogs? The Denver Broncos, who hadn’t ranked higher than eighth on their list between the time John Elway retired and when Peyton Manning joined the team.

Ahead of the Cowboys in the second and third spots, respectively, are the New York Giants and Green Bay Packers. After the Cowboys in fifth place are the Pittsburgh Steelers, followed by the Seattle Seahawks, who have roared up from their bottom-rung rankings (31st in 2010, 27th in 2011) since winning the Super Bowl.

Those polled also believe that the Seahawks — ahead of the Broncos — are the team to beat in the Super Bowl this coming February.

So who are the least-popular teams in the NFL? The bottom five: Carolina Panthers, St. Louis Rams, Tampa Bay Buccaneers and — tied for last — the Tennessee Titans and Jacksonville Jaguars. The Jaguars had been the least-popular team by themselves for four years running.
