Dan Dierdorf and Greg Gumbel were paired up by CBS prior to the start of the 2006 NFL season, so this is their seventh together. Dierdorf proved that he may literally not know an ass from an elbow during an official review today and, as you can hear above, is also calling Greg Gumbel "Bill." There's some discussion around the virtual office that Dierdorf may have said "I feel Jacoby Jones should return every kick," but that doesn't sound like a Dierdorf construction to me, and he doesn't seem to have had a great game overall, so a "Bill" isn't out of the question:
Greg Gumbel is either a little miffed this afternoon, or the forgotten Gumbel—Bill Gumbel—is finally making his mark.
