The Broncos set a single-season record for points scored this year, making for an intriguing battle when they come up against a Seattle Seahawks defense that led the league in scoring defense, total defense, pass defense and interceptions.
One of the most noteworthy members of the Seahawks defense is cornerback Richard Sherman, who was criticised for an outburst following the NFC championship game, but Decker insists that his side let their performances speak for themselves rather than trash-talking opponents on the field.
"I'll speak for ourselves - I think this team, with what we've accomplished, we're a confident team. But also at the same time, we've got to play 60 minutes of football and I think we're pretty humble about it," Decker told reporters.
"Not to say or take away from anyone else, I just think no one on our team has really maybe that ability. But I think you're trying to catch your breath instead of talking because Peyton [Manning] goes so fast. You just get to the line and get ready for the next play.
"We know what it takes to win. We don't need to talk about it, we need to play about it, and I think that is what has gotten us to this point. We all respect one another and we have fun doing it - and challenging one another, competing out here on the practice field. We just carry that over to the games."
The Broncos will be appearing in their first Super Bowl since 1998.
