Notice that Calhoun’s name is the only one mentioned in the story as a possible candidate. Surely someone inside the organization already is floating Calhoun’s name.
Calhoun was an assistant for the Broncos under Mike Shanahan from 2003-05, then served as offensive coordinator on Gary Kubiak’s staff in Houston in 2006.
At first glance, it seems far-fetched that a Mountain West coach would be looked at as a NFL head-coaching candidate. Given Calhoun’s Denver connections, it makes much more sense.
