Per Sean Callahan and the HuskersOnline gang, former Conneticut Head Coach & Notre Dame Defensive Coordinator Bob Diaco is in Lincoln right now.
The report states that he is interviewing with Mike Riley & Nebraska Football staffers for the Defensive Coordinator job opened by the Mark Banker removal.
The kicker is that Diaco was also rumored to be looking to become either DC or Co-DC at Arkansas, where he may join forces with former Iowa State HC Paul Rhoads.
DC update: Sources seem clear that 3-4 guy might be the direction. Smoke around one candidate.
