Last year, the defenses in the AFC West ranked as follows: Den #1, SD #8, KC #14, and Oak #23 according to FO. What has changed?
Denver threw big FA bodies at and are trying to develop a more stout interior DL. Their only real loss was at DC (Phillips) and it could be a big one. But they hired a Phillips protege as HC and promoted from within at DC so I suspect the D will be one of the best again.
Even with all their injuries last year, SD's D was surprisingly stout between the 20's. With the return of their #1 CB and some help at safety, the Chargers' DL, led by Bosa and Ingram, can be legit again. They added a defensive minded HC and Rivers and the O should have a much better year. I get why some are projecting the Chargers to win the AFC West, especially if their D is in the Top 10 again.
Even with injuries to Houston and at inside LB, KC's D won the AFC West last year by scoring and generating turnovers and redzone stops. Hard to bet against that D, which kept the band together and replaced its one loss (Poe) with another good DT. That said, if the D, which bends a lot, breaks more, it could play closer to its ranking.
Well, that brings us to the Raiders' #4 D. How far down in the cellar the D remains will dictate whether the Raiders win the AFC West (IMO). Got to think the secondary not only underperformed last year, but upgraded significantly this offseason with Pagano, two high draft choices, last year's 1st round choice getting healthy/better, and the departure of DJ. The edge of the D remains stout. We could have 3 new starters on the DL, including the return of a good player. And we hope Red's not done at ILB or somebody surprises (like Toomer in SD) and steps up.
