Yes he is, but look for Werner to get that position. There could be more to this hire I've not heard about but don't pencil him in with that QB coach type position in mind.
Just because Werner hasn't been announced doesn't mean he's not going to be announced. See the last with Daboll and his announcement timeline, ya know? And, keep in mind that the NCAA and Ole Miss come in play here as well. Any assistant leaving is going to be looked at in depth and cleared by the NCAA before they can move on. All of them do. I'm not suggesting Werner had any involvement and won't get cleared. But, he certainly won't be hired until he is.
I mentioned in the other thread he's been in Tuscaloosa recently. I wouldn't be surprised if we hear an announcement soon and he moves into an analyst/personnel guy.
