Jerry Jones was obviously a successful business executive before he became the Cowboys chief executive. To be consistently successful in business or in running any large organization, there must be specific responsibility for the ultimate performance. Who owns that responsibility for the mediocre Cowboys performance over the last 10-15 years? Jerry Jones does. His refusal to hold Garrett accountable for some measure of reasonably consistent improvement has held all die-hard Cowboys fans in mediocre-land year after year.
You want a different outcome you need to change what hasn't worked in the past. Change Garrett and most of the Staff. Can't do much worse unless we want to continually accept annual records like the Jets, Dolphins, Cincy, Bears, etc year after year.
