Most likely it was a scapegoat move on Moore. Especially since he was picked up so quickly by the Chargers for their up and coming stud at QB.
It was a great move for Moore where his success there with a top 5 offense will escalate him much faster to a HC opportunity.
The Cowboys have proven this era to be more of a dead-end for coaches this era. It’s where their career ends or last stop for most of our HC and none of our asst coaches I recall have been promoted to HC on another team since Jimmy left.
Jason Garrett was picked up quickly. Moore is just on hold as the next Jason Garrett or as Jerry said about Garrett "his Tom Landry".
It is sacrilege to use Garrett, Moore and the Great Tom Landry in the comparison sentence. That shows you what Jerry Dumbo GM Jones is for Dallas Cowboy fans.
Mike Zimmer, Tony Sparano, Sean Payton (he has a nice coaching tree developing), Todd Bowles, Dave Campo The Clown, Les Miles, Maurice Carthon, Anthony Lynn, Todd Haley, Paul Pasqualoni, Matt Eberflus, and Rich Bisaccia all got Head Coaching jobs in the NFL or College after leaving the Arlington Jonesboys (post Jimmy Johnson). NFL is a who you know business. If you knew Bill Parcells, you are going to get a look at being Head Coach. Eberflus and Bisaccia escaped Jerry Jones island. You know who promoted Campo the Clown to Head Coach after firing a Head Coach that went to back to back playoffs his 1st 2 years (Chan Gailey).
