'Football 301' diagnoses fatal flaws of 6 NFL contenders: What could derail Bills, Chiefs, Seahawks and more?

In this week's episode of Yahoo Sports' "Football 301" podcast, host Nate Tice and guest Derrik Klassen of The Athletic took a microscope to the NFL's contending teams and identified the fatal flaws that could keep each from grasping the Lombardi Trophy. Despite a surging pass rush and another dynamic year from QB Josh Allen, the soft underbelly of this Bills roster is the coverage unit. Klassen pointed out that the corners and safeties aren't making the grade, notably with players like C.J. Gardner-Johnson — a red flag signing for a would-be contender.
