I agree that recruiting at QB is the most important position for a football team. We have seen that be true, regardless of offensive style run. However, I think whatever offensive style is run by the new coach (if Riley is fired), the new coach will be able to utilize the existing roster, while then looking at what type of player they want to recruit going forward.
The new coach has to recruit the type of player that is the best fit for their system. I understood why Riley was recruiting the best passers he could, even if they weren't the most mobile. That's they type of QB he likes for his system. I was encouraged when Riley was looking at recruiting dual-threat QB's for NU. The coach has to run his system. He can't worry about the system the previous coach had, or what system the next coach may have.
