Who won superbowl 20?

Under Bill Cowher's reign as head coach since 1992, the Steelers had been one of the top teams in the NFL, making the playoffs in 10 out of his 14 seasons, advancing to the AFC Championship Game six times, and making an appearance in Super Bowl XXX, losing to the Dallas Cowboys 27-17. After having finished the 2003 season with a 6-10 record and after splitting its first two games to open 2004, Pittsburgh lost starting quarterback Tommy Maddox to injury. Maddox was replaced by rookie quarterback Ben Roethlisberger, who was drafted with the 11th pick in the 2004 NFL Draft but was not expected to play during his rookie season. Nevertheless, Roethlisberger led the Steelers to victory in all of the team's 14 remaining regular season games, giving Pittsburgh a 15-1 record and making the Steelers the first AFC team ever to win 15 games. However, the Steelers lost to eventual Super Bowl champion New England Patriots in the AFC Championship Game.
