The biggest takeaway from Kansas City Chiefs preseason victory over Arizona Cardinals

I walked away from the Kansas City Chiefs 34-19 victory over the Arizona Cardinals in the preseason opener with one big takeaway:

The Chiefs have depth. Their roster is much deeper than it has been since ... well, in a long time.

The Chiefs had a couple of inside linebackers hurt, including Josh Mauga, DJ Alexander and James-Michael Johnson. And yet, a positive takeaway for me from this game is the play of the rookie inside linebackers Ramik Wilson, who had an interception, and Justin March, who has been noticed in camp. That's depth.

Jeff Allen went down with an injury early on in the game so the Chiefs replaced him with Donald Stephenson. I know the Chiefs offensive line isn't the strength of their team but if you can bring in Donald Stephenson as a backup tackle then you have some depth. (As I am writing this, I see Eric Fisher went down in camp. That would really, really test the depth.)

The Chiefs had Sean Smith, who was one of the NFL's best corners, playing on the second team. Marcus Peters, Phillip Gaines, Jamell Fleming ... and Sean Smith. That's legit depth.

Eric Berry is a second team safety. Depth.

The Chiefs roster will be trimmed down to 53 players by September 5 and the Chiefs will be cutting some good players. James-Michael Johnson may not make it at inside linebacker and he started last year. The Chiefs have an abundance of guards that they like, including Laurent Duvernay-Tardif, Paul Fanaika, Zach Fulton and even Jeff Allen. Marcus Cooper, who was a breakout rookie in 2013 before coming back to Earth, looks like the sixth corner on this team.
