On January 31, 1999, the Denver Broncos won their second consecutive NFL championship, defeating the Atlanta Falcons in Super Bowl XXXIII, 34-19. The game was played in Miami.
If you are referring to the 2013-2014 season, yes, the Denver Broncos did make the playoffs and will be playing in the Super Bowl against the Seattle Seahawks on February 2nd, 2014.
At Super Bowl XXI, that was Jeff Rutledge.

Yes, through Super Bowl XLIII that has happened 8 times. Four of those times were against teams that were also playing in their first Super Bowl: 1) Super Bowl I - Green Bay Packers 35, Kansas City Chiefs 10 2) Super Bowl III - New York Jets 16, Baltimore Colts 7 3) Super Bowl XVI - San Francisco 49ers 26, Cincinnati Bengals 21 4) Super Bowl XX - Chicago Bears 46, New England Patriots 10 Four of those times were against teams that had already played in at least one previous Super Bowl: 1) Super Bowl IX - Pittsburgh Steelers 16, Minnesota Vikings 6 - this was the Vikings 3rd appearance. 2) Super Bowl XXI - New York Giants 39, Denver Broncos 20 - this was the Broncos 2nd appearance. 3) Super Bowl XXXV - Baltimore Ravens 34, New York Giants 7 - this was the Giants 3rd appearance. 4) Super Bowl XXXVII - Tampa Bay Buccaneers 48, Oakland Raiders 21 - this was the Raiders 5th appearance. If you throw out the games where two first time teams were playing, the first time team has a record of 4-13 (through Super Bowl XLIII) against teams that had previously played in at least one Super Bowl.
The Washington Redskins beat the Denver Broncos by the score of 42-10 to win Super Bowl XXII. It was their second Super Bowl victory. The game was played in San Diego's Jack Murphy Stadium. Redskins QB Doug Williams went absolutely nuts in this game, passing for 4 touchdowns in the 2nd quarter alone to make the second half a rather anticlimactic half. Like the Redskins' first Super Bowl win in 1983, it came after a strike-shortened season. It was yet another testament to Hall of Fame Coach Joe Gibbs' ability to out-prepare opposing coaches in an extraordinarily chaotic season.
