Dallas Cowboys owner and general manager Jerry Jones wants head coach Jason Garrett to relinquish his offensive play-calling duties, ESPN reported Saturday. The Cowboys finished 8-8 this season and missed the playoffs. They are 21-19 in two years under Garrett, who has faced criticism for his clock management. Jones also reportedly wants Garrett to fire his brother, John, who is the team's tight ends coach. John Garrett is the team's passing game coordinator. Mike Florio of NBC Sports' Pro Football Talk reported that Jones is asking Garrett to stop calling the offensive plays and fire his brother as a way of getting Garrett to resign.
