That's true but these days kids want to hear from the head coach. Mario alluded to that in his NSD Press Conference.
That's what ultimately undid Mullen at UF, like you said, he didn't care for that piece of the process and you just can't be that way at a place like UF as HC.
Now, him as an OC/QB coach is an entirely different story, I'm here to say it now.....my guess is that if Saban loses Bill O'Brien to another school/NFL....don't be surprised one bit if Saban tabs Mullen as his next OC/QB coach.
That has to be the only reason he hasn't surfaced, this dude is young and is brilliant offensively, no way he's just going to hang it up......there's something up and we'll know soon enough what it is.
Suffice to say, as an OC/QB coach, I would have to say that this person doesn't have to be an elite recruiter. Personable guy, yeah, but you don't have to be DVD level "cool to the kids" type to be good at your job of coaching QBs.
I can see Mullen surfacing somewhere like Arizona State where he can just take the kids that want to come play ball, and field an elite OFF with very minimum expectations. He'd basically be the UK/Mark Stoops of the Pac-12 and IMO that's a win-win for him.
Win-Win for us is to hire him as OC/QB coach but I'm sure everyone knows my take on that by now lol
