The Dallas Cowboys defense needs an upgraded version Mazi Smith. His ability to take a serious step forward in his second NFL season will dramatically dictate what direction the pendulum swings for this group.
We are on the precipice of training camp beginning and therefore learning more about how Mike Zimmer is going to properly coordinate the bunch on a down-to-down basis, but Smith was one of the only people to not fully thrive with Dan Quinn pulling the strings. Perhaps Zimmer is the whisperer that he specifically needs.
Whether you blame the coordinator or the player something was obviously not right with Smith throughout the course of his rookie season.
