Simple plan for NFL success (assuming when things R on the up & up)

Build a solid OL for a cerebral and mature QB who can process on-field developments quickly, read defenses, make quality decisions, has above average arm talent, can throw from multiple platforms and can develop good pocket presence. Compliment that with a defense whose strength is the DL and can rush the QB and you are already better off than 80-90% of modern day NFL competition.
