I'll probably get flamed for this, but I'm going throw out a name:

Dave Wannstadt

Pittsburgh connection

Coached special teams at Pitt when he was Head coach

Was Special Teams coach for Tampa Bay Bucs (I think for a season under Schiano)

He was with Buffalo, for a spell, now I think he's out of coaching.

Just throwing it out there - I'm not for or against it, it just popped into my head. I don't know why, just popped in there.
