The Steelers won their fourth Super Bowl title to close out the 1970s when they knocked off the (Los Angeles) Rams in Super Bowl XIV. The Steelers hallmark from that era was defense, and this year's Rams team could have one of the league's top defenses.

Super Bowl XLVII will long be remembered as the Harbaugh Bowl as it featured two brothers (Jim and John Harbaugh) as opposing head coaches. But this game will take on a different feel as Jim left the 49ers to coach his alma mater, the University of Michigan.

The AFL made it two-in-a-row when Len Dawson and Hank Stram led the Chiefs to a win over the Vikings in Super Bowl IV. Now Andy Reid enters his third season as coach of the Chiefs, while Mike Zimmer is in his second season in charge of the Vikings.

The franchises have split a pair of Super Bowl matchups, including the Dolphins triumph over the Redskins to cap a perfect season in Super Bowl VII. Both franchises need a ton of work to get back to that level, though the Dolphins made a huge splash with the acquisition of Ndamukong Suh in the offseason.

The Bengals reached the Super Bowl twice in their history, but had to face Joe Montana and those loaded 49ers teams of the 1980s. The Bengals appear to hold the talent advantage headed into this year's matchup with all the departures in San Francisco.

The Jets shocked the football world when they knocked off the NFL's (Baltimore) Colts in Super Bowl III, which gave legitimacy to the AFL. The Jets, under first-year coach Todd Bowles, could earn some legitimacy if they could knock off the Colts who are one of the favorites to win the AFC.

The Cowboys became the first club in Super Bowl history to hold their opponent without a touchdown when they defeated the Dolphins in Super Bowl VI, and Tom Landry's first Super Bowl win as coach. The Cowboys enter this season with Super Bowl aspirations.

The Packers won back-to-back Super Bowls after they took down the Raiders in Super Bowl II. The Packers enter this season as one of the favorites to represent the NFC. The Raiders have struggled in recent years but do have a young QB in Derek Carr which makes them interesting.

The Packers won the first Super Bowl when they overwhelmed the Chiefs in the AFL-NFL Championship Game (as it was called in those days). Bart Starr was the quarterback of the Packers during that dynasty and Aaron Rodgers has carried on the legacy of Green Bay QBs.

The Saints pulled out all the stops, included an onside kick to open the second half, to defeat the Colts in Super Bowl XLIV. The Saints again pulled out all the stops this offseason to improve the defense as they traded Jimmy Graham to the Seahawks in a stunner.
