The NFL’s AFC East has been thoroughly dominated by the Patriots in the last decade and a half. Over that time, they have made seven Super Bowl appearances and won four of them.

Meanwhile, the other three teams in the AFC East (Bills, Dolphins, and Jets) don’t have any Super Bowl appearances between them since the Bills lost in four straight Super Bowl appearances during the 1990-93 seasons.

According to CBS Sports, the Patriots are once again heavy favorites to make the playoffs. They have -1500 odds meaning someone would have to bet that much just to make $100.

The Bills are +450 (bet $100 to win that much) while the Dolphins and Jets are +600.

Here are the key additions and losses from each of the four teams in the AFC East.

Buffalo Bills

  • Key additions: Jeremy Kerley, WR (signed), Marshall Newhouse, OT (signed), Russell Bodine, C (signed), A.J. McCarron, QB (signed), Trent Murphy, DE (signed), Star Lotuleli, DT (signed), Chris Ivory, RB (signed), Vontae Davis, CB (signed), Josh Allen, QB (first round), Tremaine Edwards, LB (first round), Harrison Phillips, DT (third round)
  • Key losses: Richie Incognito, G (retired), E.J. Gaines, CB (Browns), Preston Brown, LB (Bengals), Shareece Wright, CB (Raiders), Deonte Thompson, WR (Cowboys), Jordan Matthews, WR (Patriots), Tyrod Taylor, QB (Browns)

Fresh off their first playoff appearance since 1999, the Bills will have a new starting quarterback after trading Tyrod Taylor to the Browns.

In his three seasons with Buffalo, he completed 62.6 percent of his passes for 8,857 yards, 51 touchdowns, and just 16 interceptions.

The team signed A.J. McCarron away from the Bengals. He has shown potential but only made three starts (plus one in the playoffs) in his four-year career.

Josh Allen was taken with the seventh overall pick out of Wyoming.

He may not be ready to take the reins to begin the season, but Buffalo may feel pressure to put him in from the fans if the team gets off to a tough start.

Miami Dolphins

  • Key additions: Akeem Spence, DT (trade), Frank Gore, RB (signed), Josh Sitton, G (signed), Danny Amendola, WR (signed), Daniel Kilgore, C (trade), Albert Wilson, WR (signed), Robert Quinn, LB (trade), Minkah Fitzpatrick, S (first round), Mike Gesicki, TE (second round), Jerome Baker, LB (third round)
  • Key losses: Mike Pouncey, C (Chargers), Cody Parkey, K (Bears), Jay Cutler, QB (retired), Jermon Bushrod, OT (Saints), Ndamukong Suh (Rams), Lawrence Timmons, LB (released), Jarvis Landry, WR (Browns)

Coming off a disappointing 6-10 season, Miami welcomes back long-time starting quarterback Ryan Tannehill after he missed all of last season with a knee injury.

He no longer will have his favorite target in Jarvis Landry as he was traded to the Browns. They did acquire a bevy of new weapons for Tannehill to throw to in wide receivers Danny Amendola and Albert Wilson while also drafting tight end Mike Gesicki in the second round.

New England Patriots

  • Key additions: Trent Brown, G (trade), Jordan Matthews, WR (signed), Cordarrelle Patterson (trade), Jeremy Hill, RB (signed), Adrian Clayborn, DE (signed), Jason McCourty, CB (trade), Danny Shelton, DT (trade), Isaiah Wynn, OT (first round), Sony Michel, RB (first round), Duke Dawson, CB (second round)
  • Key losses: James Harrison, LB (retired), Cameron Fleming, OT (Cowboys), Danny Amendola, WR (Dolphins), Nate Solder, OT (Giants), Dion Lewis, RB (Titans), Malcolm Butler, CB (Titans)

The Patriots have won nine straight AFC East division titles and have been division champs in 14 of the last 15 years.

All eyes will be on who will replace Nate Solder to protect Tom Brady’s blindside at left tackle. Solder started 82 games there from 2012-17, but he signed a hefty deal in the offseason to join the Giants.

Bleacher Report projects left tackle as the Patriots’ best position battle in training camp. The two players who will get the first crack at starting the season there are first-round pick Isaiah Wynn and 25-year-old Trent Brown. Brown was acquired from the 49ers and made 28 starts at tackle over three seasons, but most of them came at right tackle.

New York Jets

  • Key additions: Henry Anderson, DT (trade), Kevin Minter, LB (signed), Travis Swanson, C (signed), Clive Walford, TE (waivers), Thomas Rawls, RB (signed), Terrelle Pryor Sr., WR (signed), Teddy Bridgewater, QB (signed), Trumaine Johnson, CB (signed), Isaiah Crowell, RB (signed), Cairo Santos, K (signed), Spencer Long, C (signed), Avery Williamson, LB (signed), Sam Darnold, QB (first round), Nathan Shepard, DT (third round)
  • Key losses: Bryce Petty, QB (Dolphins), Demario Davis, LB (Saints), Austin Seferian-Jenkins, TE (Jaguars), Kony Ealy, DE (Cowboys), Wesley Johnson, C (Lions), Chandler Catanzaro, K (Buccaneers), Muhammad Wilkerson, DE (Packers), Matt Forte, RB (retired)

Much like the Bills, the Jets selected a quarterback early in the first round when they took Sam Darnold out of USC third overall.

While Darnold is clearly the future of the team behind center, it isn’t evident whether he will be thrown in to start right away in Week 1. They re-signed Josh McCown who is arguably coming off the best season of his career with the Jets. In 13 starts in 2017, the 39-year-old completed 67.3 percent of his passes for 2,926 yards, 18 touchdowns, and nine interceptions.

They also signed 2014 first round pick Teddy Bridgewater who hasn’t been healthy the past two seasons, but he made the Pro Bowl in 2015. With the Jets not expected to be much of a threat, it is likely Darnold will see the field sooner than later.
