I'm probably being pessimistic, but I doubt we pull Mickens from ND. They seem to really like him and can pay.
And do we really want Orphey from Rutgers? The Rutgers defense was in the bottom half of FBS and their passing defense was equally uninspiring. I don't have any greater context or insight than that, but I just don't see why we would want the guy. I appreciate the Choate connection point out by @Hookem2147, but Choate doesn't work here anymore. I just don't see compelling reasons for hiring the guy, although I'm more than happy to be set straight.
That makes me think that out of the three guys listed by Anwar (who probably knows less than dick), Sanders seems the most likely. Narduzzi knows ball and coaches a good defense, and this guy has moved up the ranks. And I don't think Pitt has enough money to spend keeping him even if they like the guy. So he could be a real possibility. All of that being said - I don't see this guy having any connection to Texas, the South, or even the NFL. I would expect one of those three things in whoever we hire, for recruiting purposes if nothing else.
So I come back around to Anwar being dumb as dirt and full of shit to boot. I doubt any of these three are really on our short list. At best, Mickens is looking for a raise and Sanders is being kept warm as an emergency option.
