Contrary to you over the top requirements, the only thing the new GM has to do is: don't overeach on a qb, if you draft a qb and hes a bust cut ties early, dont spend early picks on known injured players that every other team has removed from the board and act as if you are smarter than the other 31 teams GMs, retain good players that produce for you, be able to communicate clearly in the most basic of settings without contradicting yourself and making the organization appear to be ran by s bunch of amatuers, and produce a playoff team in a reasonable period 2-4 years.
