Obviously they WEREN'T in a more competitive league if they won 4 SB's in 6 years
How can the best team ever not be the current Pats?
Superbowl champs. 21 games IN A ROW. And all of this when there is MORE parity in the NFL than ever. in other words, ANY team can win. Nowadays its extremely difficult for a team to stay at the top. Look at the Rams, Ravens, Giants, Bucs, Raiders and Panthers...all mediocre teams who were the other 6 teams in the SB the last 4 years besides the Pats. Rams are so-so. Ravens have a good D but their O sucks. Giants are FINALLY starting to show some life. Bucs suck. Raiders are horrible and the Panthers are among the worst in the NFL.
For a team to win 21 in a row nowadays is INSANE. My vote is Pats '04
