Oh great! Another Barry Switzer.
Leave Garrett alone and let him select his own coaching staff. Garrett had his coaches foisted upon him by Jerry Jones. It is nearly impossible to run a team if your coaches aren’t of your own choice.
Garrett is a good coach. A team plagued by injuries all season and coaches who “may” have other agendas will not fix the situation. Also, the way I look at football today, wide receivers seem to be the ones causing the most internal team problems. If that is truly the case, hiring an Antonio Brown for 3-4 games would have helped the Cowboys and at the end of the season, you have a discussion as to whether he wants to be part of the family or a hired gun.
