(listed in predicted order of finish)
Projected 2020 record: 10-6
2019 record: 10-6
2019 summary: New weapons and a rebuilt offensive line helped Josh Allen take another step, while Sean McDermott's stingy defense carried the load. The Bills pushed the Patriots in the AFC East before settling for a wild-card spot and falling victim to Deshaun Watson's heroics in Houston.
Key additions: WR Stefon Diggs, DE Mario Addison, DE A.J. Epenesa, CB Josh Norman, DL Quinton Jefferson, DT Vernon Butler, G Brian Winters, LB A.J. Klein, RB Zack Moss, OL Daryl Williams
Noteworthy losses: DT Jordan Phillips, DE Shaq Lawson, LB Lorenzo Alexander, RB Frank Gore, CB Kevin Johnson, G Spencer Long
Cause for concern: While Allen has come a long way, he remains unpolished, with shaky accuracy (especially deep) and bouts of inexplicable decision-making. His mobility is still valuable, but with Diggs on board, Allen has no excuses to remain a below-average passer.
Position battle worth watching: The whole starting offensive line returned, but Jon Feliciano tore his pec, leaving a hole at right guard. Brian Winters and Daryl Williams will likely battle for the job, but it's also possible that Cody Ford -- who struggled at right tackle as a rookie -- bumps in to right guard, leaving Williams to compete with Ty Nsekhe at right tackle.
Over-Under win total from PointsBet: 9
With a very well-rounded roster, great coaching and the rival Patriots now weakened, the Bills are a relatively safe bet to contend for a playoff spot. Reaching double-digit wins will depend on health and Allen's development, but we like their chances.
2020 forecast: Buffalo's defense should keep humming and could become a juggernaut if Ed Oliver takes a leap. Even if Allen's progress stalls, offensive coordinator Brian Daboll is terrific at manufacturing big plays, and the Diggs addition gives him one of the league's best set of weapons. The Bills are the slight favorites in the division, but they'll need more from Allen to threaten Kansas City and Baltimore.
New England Patriots
Projected 2020 record: 9-7
2019 record: 12-4
2019 summary: A historically great defense -- led by Defensive Player of the Year Stephon Gilmore and a shutdown secondary -- had Patriots fans eyeing another 16-0 regular season, but the offense never clicked and came up short in a home playoff loss to Tennessee, Tom Brady's final game as a Patriot.
Key additions: QB Cam Newton, C David Andrews, DT Beau Allen, LB Brandon Copeland, S Adrian Phillips, S Kyle Dugger, LB Josh Uche, LB Anfernee Jennings, TE Devin Asiasi, K Justin Rohrwasser
Noteworthy losses: QB Tom Brady, LB Dont'a Hightower (opt-out), LB Jamie Collins, LB Kyle Van Noy, S Patrick Chung (opt-out), RT Marcus Cannon (opt-out), DT Danny Shelton, FB James Develin, TE Matt LaCosse (opt-out), WR Phillip Dorsett, LB Elandon Roberts, K Stephen Gostkowski
Cause for concern: Newton's health is obviously the biggest X-factor, but close behind would be the rash of opt-outs due to COVID-19. Some even added uncertainty at weak positions, with Hightower now gone from an already depleted linebacking corps and LaCosse's departure leaving no veterans of note at tight end.
Position battle worth watching: Belichick loves do-it-all linebackers and safeties to run his simulated pressures, but with Hightower, Collins, Van Noy, Roberts and even Chung gone, the Patriots need several youngsters to emerge. Ja'Whuan Bentley (inside) and Chase Winovich (outside) will play major roles, but Uche and Jennings must adapt quickly. Dugger, a big, physical safety, will battle veteran Adrian Phillips for early playing time.
Over-Under win total from PointsBet: 9
Opt-outs aside, a healthy Cam Newton would likely make the Patriots at least co-favorites in the AFC East, but betting on his health is dicey. Still, faith in Bill Belichick makes the over tempting, although it might be better to avoid this one altogether.
2020 forecast: Belichick and Josh McDaniels adapt as well as anyone, which is why AFC East opponents should be scared if Newton is healthy. Belichick should find enough bodies to keep the defense sharp, but personnel losses and likely turnover regression make the margin for error slim. A wide range of outcomes -- from 12-4 and Super Bowl contenders to 6-10 if Jarrett Stidham plays -- are on the table.
New York Jets
Projected 2020 record: 7-9
2019 record: 7-9
2019 summary: Derailed early by Sam Darnold's bout with mono, the Jets cobbled together a surprising 6-2 stretch to close the season. While it came against a weak schedule, that run -- and Darnold's strong play -- created optimism for 2020.
Key additions: OT Mekhi Becton, OT George Fant, WR Breshad Perriman, C Connor McGovern, WR Denzel Mims, CB Pierre Desir, LB Patrick Onwuasor, G Greg Van Roten, RB Frank Gore, QB Joe Flacco
Noteworthy losses: S Jamal Adams, LB C.J. Mosely (opt-out), WR Robby Anderson, CB Trumaine Johnson, LT Kelvin Beachum, RG Brian Winters, C Ryan Kalil, WR Demaryius Thomas, RT Brandon Shell, LB Brandon Copeland, WR Josh Doctson (opt-out)
Cause for concern: GM Joe Douglas has done a lot of work, but is there enough talent to continue 2019's second-half surge? The overhauled offensive line will need growth and chemistry, and Darnold still lacks great weapons. The defense lost its two best players in Adams (trade) and Mosely (opt-out), putting more pressure on coordinator Gregg Williams.
Position battle worth watching: Douglas added two viable options at tackle in Becton and Fant, but neither is a sure thing. Becton will likely slot in at left tackle, leaving Fant to battle 2019 third-rounder Chuma Edoga, who struggled as a rookie but has excellent tools. Fant has never been a regular starter but was paid like one.
Over-Under win total from PointsBet: 6.5
The Jets beat this total last year despite Darnold missing three games, so it's fair to expect better, especially with Darnold adding experience and the Patriots now weakened. Even so, Adams' trade and Mosely's opt-out would make us a bit cautious.
2020 forecast: After a bizarre sophomore campaign, Darnold must show progress in 2020, but it's not all on him. The quantity-over-quality approach on the offensive line might not fix things immediately, especially if Becton transitions slowly. Add in a defense that lost Adams and Mosely, and it's hard to see the Jets as a serious contender to claim the division.
Projected 2020 record: 6-10
2019 record: 5-11
2019 summary: Historically awful for the first half of the season, the Dolphins certainly didn't quit, riding veteran Ryan Fitzpatrick to five one-possession victories down the stretch, including spoiling the Patriots' bid for a playoff bye.
Key additions: CB Byron Jones, QB Tua Tagovailoa, LB Kyle Van Noy, OT Austin Jackson, G Ereck Flowers, DE Emmanuel Ogbah, DE Shaq Lawson, RB Jordan Howard, RB Matt Breida, C Ted Karras, CB Noah Igbinoghene, OL Robert Hunt
Noteworthy losses: S Reshad Jones, DE Taco Charlton, DE Avery Moss
Cause for concern: Jackson, Flowers, Karras and Hunt provide options along the offensive line, but will it be enough? Jackson has far more potential than polish for now, and Hunt's transition from the Sun Belt could be rocky. Flowers has all of one adequate season on his resume, and Karras' only campaign as a starter was shaky. The stakes are high given Tagovailoa's injury history.
Position battle worth watching: Tagovailoa won't be battling Fitzpatrick as much as the team's plan to be patient with the lefty from Alabama. By all accounts, Tagovailoa is fully healed from hip surgery, but how slowly will the Dolphins bring him along? Fitzpatrick's leash might be longer given the lack of a preseason.
Over-Under win total from PointsBet: 6.5
After making so many upgrades, Miami probably hopes to leap near .500, but rebuilding rarely proves so linear. The Dolphins outperformed their point differential by a wide margin in 2019 and likely won't be so fortunate in close games. We'd expect some bumps and bruises, even if Tagovailoa plays early.
2020 forecast: The Dolphins didn't lose many players of note and made a host of key additions, including reinforcements in both trenches and a potential franchise quarterback. But much of the free agent spending felt like empty calories, and the draft class -- while big -- includes several players who need significant development. The goal should be progress and a smooth transition for Tagovailoa, with an eye on competing in 2021.
