Obviously I'm biased, but I think I have the best team in this division right now.
Coaching Staff: Bill Belichick is the best HC in football right now and it isn't close.
Offense: Tom Brady is suspended 4 games, but he is still one of the best QBs in the game and Paxton Lynch provides a QB for the future. Jamaal Charles and Danny Woodhead provide a good 1-2 punch that fit the NE offensive scheme and are playmakers. Martellus Bennett and Dwayne Allen provide a talented 2 TE set and can both block and give Brady another good TE group. Julian Edelman is Brady's favorite WR and the perfect scheme fit while Kamar Aiken quietly had a good season and is in line for another one. The OL of Joe Thomas, Joel Bitonio, Matt Paradis, Brandon Linder, Bryan Bulaga is probably at least top 3 in the game.
Defense: At DE Michael Bennett is and elite pass rusher and run defender while Junior Galette is a high-level pass rusher and Devin Taylor had 7 sacks playing 50% of the Lions snaps and provides insurance for Galette and will play a lot when Bennett kicks inside. DT Jurrell Casey is a borderline elite player who excels vs the run and pass and Steve McLendon is a good run-stuffing NT, which is all I need. Only 2 LBs as I chose a 5th DB over a 3rd LB, but DeAndre Levy is one of the best WILLs in the game and Ben Heeney is a rising player who played well when he took over as a starter last year. At CB, Malcolm Butler has become a top CB, Joe Haden has been a top CB in the past and is still young and Buster Skrine is a solid #3 option and is in a good spot to succeed. At S, neither Eric Reid or Ron Parker are top talents, but both are solid players who are best in coverage and Parker can move all around and even play slot CB.
I don't think there is a standout team for the best in 3 years. I honestly could see all 4 of them being the best.
For my team, I have older players and people in their primes now and not many players still on rookie contracts, but if Paxton Lynch develops well him and Belichick could do a lot of damage and my interior OL are all 3rd or 2nd year players.
