The AFC East is home to two of the best defenses in the NFL last year in the Buffalo Bills and Patriots, while the Miami Dolphins look like they will enter the 2020 season much improved.
With the New England Patriots losing some key defenders this offseason but gaining some valuable youth through the draft, and the Buffalo Bills upgrading on defense these two defenses should be plenty strong. With Miami completely overhauling their defense there are many new players that have invaded the division. The New York Jets made their big splashes last year and kept it status quo on the defensive side of the ball, not making too many changed to their defense.
