There are many legitimate criticisms of Garrett. He's made a few bone-headed moves too. Tony Romo (and many others) made some mistakes too. It happens in football. I still firmly believe that the lack of success in recent history is all about front office mistakes. Bad personnel decisions (drafting, roster, contract) have doomed the Cowboys. The good news is I think we are improving in this area, but is Dak a championship level QB, capable of spreading out a defense? If Dak is not, are we going to blame Garrett for that too?
If this team had a true championship roster and failed, then we could blame the coaching. That was not the case.
