For arguements sake, Chow gets the HC gig in AZ. There is an opening at OC. The Titans saw some excellent years offensively with Dinger as OC and most importantly Dinger likes the shotgun(Chow doesnt use it as much as Dinger did). Vince is more comfortable in the shotgun. Dinger is a assistant HC in Denver, would Dinger be willing to come back as an OC.
