The Denver Broncos learned a hard Super Bowl lesson two years ago.
They went into the championship game with the NFL's top-ranked offense and got blown out.
So the Broncos changed the formula. They built a dominant defense. A defense, as it turns out, for a generation.
Linebacker Von Miller on Sunday led an onslaught that threw NFL most valuable player Cam Newton off his game and gave the Broncos a 24-10 victory over the Carolina Panthers in Super Bowl 50 at Levi's Stadium.
The victory made Hall of Fame-bound quarterback Peyton Manning a two-time Super Bowl champion and sent him off to ponder retirement after a 15-4 season.
