The Kansas City Chiefs have several big name star players on defense. Guys like Justin Houston, Marcus Peters, and Eric Berry are all among the very best at their positions already, and they have a couple other ascending talents in Chris Jones, Reggie Ragland, and the newly acquired Kendall Fuller. Those six players make up about half of their starting defense.
With that many quality players, you would think the unit would be a force to reckon with. Unfortunately, in 2017 the defense was a disappointment. The return of Berry from injury and the acquisition of Fuller should help this defense but they are going to need more new blood added to the mix (especially in the front seven) if they want the defense to be significantly better in 2018.
