In the last 30 years only 3 teams have won more than 2 Super Bowls and they are:
Patriots (6), Cowboys (3), Broncos (3).
In that same time frame 5 other teams have won 2 Super Bowl titles and they are:
Packers (2), Steelers (2), Giants(2*), Buc's (2), Ravens (2).
The 30 games are rounded out with 8 teams who won a solo title and they are:
Eagles, Redskins, Seahawks, Rams, Saints, 49ers, Chiefs, Colts.
*Giants would have 3 if the time-frame were expanded to 31-years.
Two (2) seems like pretty goof company to me...
