The Talk: Most knowledgeable fans?

Which NFL cities have the most knowledgeable fans?

Eric Allen: Chiefs fans: Chiefs fans know the coverages you're playing as well as every player on both teams. It's not a lot of fun playing in that stadium as a visiting player, but it would've been fun to have played there.

Packers fan are next in line. What more can be said about one of the great football cities in the country? Green Bay fans are extremely knowledgeable and passionate about their teams, almost to the point of obsession. Speaking of obsession, Eagles fans are some of the most obsessive about their team in the NFL. They care and they aren't afraid to let you know it on and off the field. I'm not sure what it is about Pennsylvania and football fans, but Pittsburgh brings the noise and knowledge every week.

Joe Theismann: Steelers fans: The Steelers have fans all over the world -- and they don't just know football, they live it. In addition to Steelers fans, Packers, Redskins, Cowboys and Giants fans are also very knowledgeable. Packers fans absolutely live and breath football. They look forward to the season from the end of the last NFL season. The Redskins have great fans, too. I had the pleasure of playing for this organization, so I know from personal experience how great the fans are and how much they know about the history of this game.

As a former Redskin, it pains me to put Cowboys fans on this list, but their fans are fantastic. They know their football and do a great job supporting their team. Following the NFC East trend, the Giants also have great fans. If you make it here, you can make it anywhere. How true. Giants fans know their football, and if you're a great player, there aren't many other places you'd want to play.

John Clayton: Steelers: The Super Bowl in Detroit illustrated the passion and resourcefulness of Steelers fans. They had about 80 percent of the seats in Ford Field. It's a city known for its love of great defenses. Four Super Bowl championships in the 1970s educated the fans on the type of players and schemes that are successful in the NFL. Pittsburgh knows football.

Around the country, Browns fans are everywhere. Booster groups are in just about every city, but the base is in Cleveland. Fans survived Art Modell's move to Baltimore and the time awaiting an expansion team. Things have been tough since the Browns came back, but the fans still sell out the stadium and push the front office to make the right moves.

Chicago is a great sports town and the fans know the games. Even though the city is big enough to support two baseball teams, pro football is the main topic. Bears fans love their defense, and those who run the Bears know they better play to their fans.

Philadelphia may be the City of Brotherly Love, but it's a tough sports town. Listen to the talk shows. There is an edge to the calls. It's hard to trap them on a subject. Eagles fans know the game and they are willing to express their opinions.

The Cowboys -- America's team -- have some of the best fans around. They travel to training camp, whether the location is Oxnard, Calif., or San Antonio. Owner Jerry Jones knows how to play to those fans. The Cowboys are one of the model franchises in sports, but so much of it is because of the fans.

Len Pasquarelli: Eagles: Philly fans are crazy, but their passion is equaled by their knowledge of game. Pittsburgh and Cleveland fans also rate very high on any list of the most knowledgeable NFL fans.
