Kansas City Chiefs: The Chiefs have an actual offensive line now, meaning they are back as the league's best team.
Buffalo Bills: They have all of the necessary pieces, that is if Josh Allen can repeat or better his stellar season last year to be a legitimate threat to Kansas City.
Tennessee Titans: Tennessee's third down defense (getting stops 48.1% of the time) was the worst in the NFL in 30 years. Being just average would do wonders for this team.
Cleveland Browns: Remember that Odell Beckham Jr. missed the Browns final 11 games, including the playoffs. This offense should be tough to stop.
Baltimore Ravens: In the Ravens final five regular season games last year they averaged 37.2 points. With a bunch of new receivers, their problem coming from behind could start to be fixed.
New England Patriots: New Quarterback, new tight ends, two new receivers. The Patriots also get back and add some significant pieces to their defense.
Indianapolis Colts: The Colts have the depth at receiver to help out Carson Wentz, but this defense will still need to carry the Colts for them to make the playoffs.
Pittsburgh Steelers: The Steelers have plenty of star power on both sides of the ball. Their collapse last year was ugly though, and Ben Roethlisberger is now 39 years old.
Miami Dolphins: This season truly is all about Tua Tagovailoa. We know the defense is going to force a lot of turnovers, Miami just needs their offense, now full of speedy receivers to execute.
Los Angeles Chargers: We all remember Justin Herbert's stellar rookie of the year winning season, but the Chargers still went 7-9 last year and have a largely new coaching staff. Still this team could be dangerous.
