After adding Peyton Manning last season and earning the AFC's top seed in the playoffs with a 13-3 record, the Denver Broncos lost in heartbreaking fashion to the Baltimore Ravens in the divisional round 38-35 in overtime.
But they'll be back in a big way, Miller believes.
Well, we certainly can't accuse Miller of a lack of confidence, now can we?
Of course, Miller has earned a little braggadocio. Just two years into his NFL career, he's already accumulated 30 sacks, 105 solo tackles and eight forced fumbles. The man is a beast and a big reason why the Broncos will go into 2013 as a Super Bowl contender, with or without his lofty predictions.
After all, take away some shoddy defending late in the game against the Ravens that led to Joe Flacco's 70-yard, game-tying strike to Jacoby Jones with just 31 seconds remaining, and perhaps Miller's guarantee would be about repeating as Super Bowl champions.
Miller's prediction isn't just all about cockiness, confidence and swagger. The hybrid linebacker is dedicating the Broncos' pursuit of the Lombardi to his cousin, Jeremiah, who just came out of a coma.
This Broncos team is pretty stacked. Manning revitalized the passing game, while the defense was once again one of the best in the league, holding opponents to 199.6 passing yards and 91.1 rushing yards per game, both third-best in the NFL.
After starting the season 2-3, the Broncos rattled off 11 straight wins heading into the playoffs, and many were surprised when they failed to beat the Ravens in Denver.
So really, Miller's prediction isn't that crazy. While it may be a bit early to be making predictions about next season, it's safe to say Denver is one of a handful of teams that has a legitimate shot at winning the Super Bowl next year.
