We've heard it alluded that Frank would have rather signed Derek Carr than draft a QB at all. Obviously that didn't happen, so why again do we believe that Wilks would have the power to overrule the front office/scouts/Tepper who all wanted to draft and develop a QB? You have repeatedly cited rumblings that Reich preferred Stroud over Young - why do we believe there would have been a different result with Wilks even if he had the same opinion?
Even if I concede that he wrote the playbook, honestly plays are similar, if not the same in many instances, across the league. That being said, having plays is half the battle (or less), it's actually Knowing when to call them that counts. Of course you should also be trying to run the plays which best fit the strengths of your personnel, and players have to successfully execute the plays as well.
