1. Mark Whipple has been hired as OC at OU. 2. Jeff Lebby has been hired as OC at OU.
Not really a big deal, just kinda funny that neither story mentions the other (Whipple was hired first) and neither mentions co-OC.
My guess is, whether they call the co-OC or not, that in reality Lebby will be the OC (he'll be in the booth calling the plays) and Whipple will be the QB coach. It will be Lebby who establishes the style of offense they run and Whipple will be tasked with preparing the QB to run that offense.
