Hopefully, Coach Stoops will find an OC that will be totally compatible with his offensive philosophy (whatever that is), so that OC and head coach are on the same page. After watching two OCs from the "air raid" tree with decent to good success elsewhere all but abandon the vertical passing game and fail miserably under Stoops, one has to question what type of offense Stoops really wants to run.
Furthermore, any OC, no matter how experienced and how good, will have his hands full in developing an OL that can actually pass block, a receiving core of stone-handed receivers, and running backs that can't or won't pick up the blitz.
