Remember the last full-time head coach for the Cowboys who handled the head coaching duties as well as being a coordinator?
His name was Wade Phillips, and while many Cowboys fans might be trying to erase that name from their memories, Phillips was a great defensive mind and not a great head coach.
To put it simply, there aren't many guys out there who can manage both duties. Calling a play, handling timeouts, handling challenges, being a respected guy by the entire team, so and so on. A head coach is supposed to be run the entire team, and when he is a coordinator he spends all of his time with that side of the ball.
Remember when Wade Phillips didn't even know Marion Barber got hurt a couple of years ago? That kind of stuff probably happens more than we think in those situations.
A head coach needs to be just that, a head coach. Jimmy Johnson, Bill Belichick, the list goes on. Most of the highly successful NFL head coaches have coordinators to do that part of the job. After all, part of what makes a great head coach is having great assistants.
Garrett is a great offensive mind, but he's not the only one out there.
There is an astronomical amount of NFL head coaches who lost their jobs this season. Bring in one of those guys. Or bring in someone who's been out of football for a couple of years that's an offensive guy and has head coaching experience, someone like Brian Billick.
Look at the Chicago Bears coaching staff this year. Lovie Smith is still the head man and has gone from the hot seat to a first-round bye in the playoffs. Look how he did it. Mike Martz, a former NFL head coach, is his offensive coordinator, and another former head coach, Rod Marinelli, as his defensive coordinator. Marinelli went 0-16 as a head coach but has a heck of a defense rolling in Chicago. That just goes to show there's plenty of guys out there who might not even be high-profile names who can run an offense or a defense.
So Cowboys fans should be knocking down Jerry's door and telling him to hire Garrett as the head coach, and nothing else.
