There hasn't been a repeat Super Bowl champion since the New England Patriots accomplished the feat in 2003 and 2004.
Fifteen years later, Tom Brady and Bill Belichick are hoping to become the second head coach/quarterback duo to win back-to-back titles twice. The only duo to do it was Pittsburgh Steelers head coach Chuck Noll and quarterback Terry Bradshaw. Noll and Bradshaw both are in the Pro Football Hall of Fame, and Brady and Belichick will one day join them.
Just getting to the Super Bowl again would be a historic accomplishment for the Patriots. It would make them the second team ever to reach the Super Bowl four consecutive seasons, joining the Buffalo Bills of the early 1990s.
What are the chances of the Patriots advancing to another Super Bowl?
John Breech of CBS Sports recently did a ranking assessing the difficulty of each team's path to Super Bowl LIV in Miami. The formula used three main factors: schedule difficulty, Super Bowl odds and the first three games of the season. Breech found that teams starting worse than 2-1 over the first three weeks rarely wind up in either the AFC or NFC Championship Game.
The Patriots actually have the easiest road. Here's what CBS Sports had to say about the Patriots' path.
32. New England Patriots
Based on our formula, the team with the easiest road to Super Bowl LIV is the New England Patriots, which probably won't come as a surprise to anyone, because the Patriots seem to have the easiest road every year. Although it seems like a vast NFL conspiracy to keep the Patriots on top, the fact of the matter is that we really just need to blame the Jets, Bills and Dolphins for not being competitive at all over the past 20 years. Anyway, we should probably just all save ourselves some time and go ahead and pencil them the Patriots in for the Super Bowl.
Schedule difficulty rating: 84.375
The team with the toughest path to Super Bowl LIV is the Chicago Bears.

If you go by a strict strength of schedule ranking, which CBS did not do in its study, the Patriots have the second-easiest schedule in 2019 based on their opponents' win percentage (.473) from 2018.
The Patriots went 11-5 last season, and it was their worst record since 2009. They did not secure homefield throughout the AFC playoffs, but they overcame it by defeating the Kansas City Chiefs in overtime at Arrowhead Stadium to win the AFC Championship Game.
New England's schedule for 2019 has the defending champs well-positioned to earn the conference's top seed and ensure the road to Super Bowl LIV again goes down Route 1 in Foxboro.
