Saying Moore has no coaching experience is like a lot of people say when trying to get a lot of jobs - how can I get experience if nobody will hire me and let me get some?
In other words, you have to start somewhere. Moore is apparently going to be the quarterbacks coach, but I seriously doubt he'll be totally responsible for Dak's development, Linehan will probably have a lot to do with that as well. The receivers coach will likely work with Moore and Dak as well.
And while I don't know since I'm not on the coaching staff, I hardly think Moore will be allowed to do whatever he thinks with Dak and will have to run it by Linehan, etc., at least for a year or two.
Can't get too hung up on somebody's title
Moore can get a start in coaching, like most guys do............ start as an assistant to the assistant, like a quality control coach. There he can get his foot in the door. I think people are purposely trying to undersell the role of a QB coach because deep down they realize this is a peculiar hire.
Look at Doug Pederson. After retiring from the NFL, he was a high school coach for a few years before Andy Reid hired him with the Eagles........... as a quality control assistant. Also on the Eagles, one of the hotter names in terms of potential head coaches down the road is their QB coach - John DeFilippo. His coaching career started in college where his first big job was a grad assistant at Notre Dame before eventually landing a job in the NFL as a quality control coach.
Sean McVay? Started as an assistant to the assistant in Tampa.
If the Cowboys wanted to throw Moore a bone, then make him a quality control assistant, etc. My fear here is that Garrett and Linehan were stubborn and didn't want any outside voices making waves in their offense.......... Dak and Moore get along and Moore buys into Linehan and Garrett's system. So let's just go hire him and make it easy on all of them.
