You are correct. Two teams have won 3 in 4 years, the Cowboys in the 1992-1995 seasons and the Patriots in 2001-2004 seasons. The Steelers of the 70s won 4 in 6 seasons, back-to-back championships twice, 1974-1975 seasons and 1978-1979 seasons.Sarty said:No team has ever won 3 in a row either AFAIK. Go Pats!
