You certainly can't think Edsall is not a realistic option giving the circumstances, his previous success here, and his current employment status.
Another name who was getting a lot of well deserved play before Diaco was hired is former OC Rob Ambrose who at the time couldn't interview because he was preparing his team (Towson University) for the FCS National Championship game, and don't forget he brought his team into the Rent 2 years ago and beat Diaco. Quality guy, great track record, and like Moorehead and Edsall he has a history at UConn.
