What this game shows us is that drafting well and signing free agents of a variable standard and making the odd good trade isn't enough to beat the Chiefs.
HTH.
I think you missed my point. None of the free agent signing were huge splashes. They were small improvements here and there. Aside from diggs.
Also, that's quite the cherry pick. All of their impact defensive starters were drafted except Micah Hyde who was also a bargain fa signing.
