At this time the Steelers are the defending Superbowl Champions so they are considered the best team in the NFL. You have good taste when it comes to picking winners.

America's Team The Dallas Cowboys. well I would say from the start but I really don't remember much before 71 when they went to the Superbowl and lost to the Colts...but through the years I think the Cowboys have been the greatest franchise in all of American sports the great history the legends the individual stories they've almost always gave all of America there money's worth.

An NFC team has won only one of the last six superbowls.  It won't be any different this year.  I think that the Cowboys are probably the most complete team in the NFC right now, but they still don't stand much of a chance against the better AFC teams.  I think it will be Chargers 35, Cowboys 17.

Pittsburgh Steelers all the way!

I think so. They won three Super Bowls. They won when they had to and beat the best teams to get there. What else can you ask of them? No team continues to dominate forever but they still have to be considered a potential Super Bowl team. I'd call that pretty awesome.\n\nI know that when I was growing up in the 70's the Steelers and the Cowboys were the yardstick that others were measured by as they won and won. Now it's the Patriots.\n\nBefore you think that I am a New Englander just touting his team I'll tell you that I live in Indianapolis and was a Steelers fan before the Colts came and now have to split my time between those two teams. The Pats sat them both down so my hats are off to them. May the best team win. Lately it's been the Patriots, Steelers, and Colts.

I would say the Falcons and the Dolphins. They should be improve next season.

The Bears...The Packers have won the most Super Bowls however

Arizona by far.  They not only had a top ten defence and offence last year, but they had the best passing game in the NFL.  With the acquisition of James, they should be unstoppable.  But with football you can never tell.

Good teams make their own luck.  So I would say they have a good team.\n\nFor more on the Ravens and the NFL, check this site out.  http://factipedia.com/sportsblogs/

Currently, Vinatieri is the best ... percentages don't always win games (right Vanderjagt!).\n\nI would have to say that either Morten Andersen or Ray Guy should be considered the best of all time.  For these guys to miss a FG would be like watching Jerry rice drop a lob pass from Joe Montana.  Guy and Andersen made kicking almost an artform in the NFL.

there are a lot of great coaches out there, but to be considered the "best", your record probably has to prove it.  with that said, i would say pete carroll of USC.  currently, he has the highest winning percentage of any active head coach.

The Dallas Cowboys are the best NFL team of all-time for numerous reasons. I'm not saying this because I am a huge Cowboys fan. They have proven it for over decades. They share the record for most Super Bowls won, 5, alongside the San Francisco 49ers and, more recently, the Pittsburgh Steelers. However, unlike the era of Jerry Rice and the Steel Curtain, the Cowboys have won with different players every time they went to the Super Bowl. They have always had one of the best defenses in the NFL, and they have the type of offense that answers back in a critical game. Sure, the Cowboys have had icons like Troy Aikman, Mike Ditka, Michael Irvin, Deion Sanders, Emmitt Smith, and Roger Staubach, and coaches like Jimmie Johnson and Bill Parcells, but the number of players that made a name under the Cowboys shows how mighty the franchise is. They can make any player into an NFL icon. Without a doubt, the Dallas Cowboys are the best NFL franchise of all time.

The Steelers are one of my fav teams, behind the niners and the bucs, but I honestly think the colts were the best team this season. but the Steelers definately had the most heart and played great when it counted

1985 Chicago Bears, because other than a fluke game on Monday night against the Dolphins they were unbeatable. One of the best teams of all time, not just my lifetime. Their defense was amazing. They had Walter Payton, one of the top three or four running backs of all time. Mike Singletary, Wilber Marshal, the Fridge, Gary Fencik, Dan Hampton, Richard Dent on D, plus they had a great offensive line and the unforgettable Jim McMahon. What a great team.

Indianapolis Colts of course. They are undefeated this year.
