As the Dallas Cowboys limp to the end of this dismal NFL season, they have a huge list of things that must be fixed in 2021. Their defense, particularly against the run, has been absolutely terrible. Fingers are being pointed at defensive coordinator Mike Nolan. That is certainly understandable. His unit has often looked baffled, as if they do not know what they need to do. While Jerry and Stephen Jones have continued to affirm that Mike McCarthy will be back for another try, they have conspicuously not offered the same assurances about Nolan. As the team’s defense threatens to set a new bar for ineptitude, it is widely assumed that his tenure is accurately described by a classic Roy Orbison song.
