I disagree with the "anxiety issues". Ex-Bills scout Smoke Dixon says the opposite....with his "cinder block" observation.
Although he did give some credence to the "mental grasp of the game is borderline average", but that was more from of observing that he did not put the work early in his career studying the game and not (at that time) being a film room rat. He admitted he does not know about his habits lately.
As I have been an persistent critic of the way Josh failed in the mental part of the game in the last 2 min of the KC loss, the title to the thread I started about that is spot on...."Requiem for the Bills - When will Josh Learn??"
Like you "I wouldn't trade Josh for any other QB in the league, bar none" but I would NOT "bet money" that "Burrows getting to another SB before Josh does.". Of course, I never bet money on football...so there's that.
There is no doubt that there is SOME "luck" in getting a franchise QB. Although it's a lot less than you seem to attribute to it, and it's a LOT less than what one of the experts and first hand observer of being a NFL QB bust, Ryan Leaf has to say.
Ironically enough, according to Leaf, simply being drafted high in the first round in today's NFL put that player at a HUGE disadvantage as the pressure is UNBELIEVABLY and DESTRUCTIVELY counter to what you want to develop a franchise QB.
Your observations of the kind of offense that Josh came into the Bills is mostly less of a factor (not to say that is not a factor) in assessing a QB's quality, at least according to NFL head coaches, NFL GM's, NFL scouts, NFL coordinators and NFL QB coaches that I have detailed with their QB Tiers evaluation.
As for my accurate observation of Green Bay's "institutional success", your lame dismissal of it as " All that's needed is the Green Bay name and voila, they automatically draft franchise QBs from now on? LOL!" shows extreme narrow mindedness and failing to see plain reality.
"Institutional success" is simply an accurate observation that the organization has developed and embraced a method of deciding WHEN and HOW to bring about continuing QB success. How the past decisions were made are PART of the ORGANIZATION which IS, in fact "institutional success"
The TOTAL OPPOSITE is what the Bills had to fall on. It was more "Institutional FAILURE". They literally had nothing to fall back on as how to succeed in transitioning the position (as players age and move on) so they mostly followed the path of failure.
I believe a very reasonable explanation for the success of Green Bay and the mostly failure of the Bills when it comes to QB's is the fact that Green Bay DOES NOT HAVE an individual owner as they have been a "publicly owned, nonprofit corporation since 1923"
NFL owners inevitability get involved with some of the most critical decisions, for better or worse (usually for worse). Almost all of them lack the necessary knowledge and experience to make decisions about football based on knowledge of experience with, you know...FOOTBALL!!!!
Today's NFL owners made their fortunes usually in business of some sort, co-foundling Home Depot, hedge fund managers, natural gas and fracking, CEO of Flying J truck stops, Texas oilman, Ford Motor Company heir, "cogeneration power plant company" owner (selling to to Enron to become rich), heating and air conditioning, car bumpers manufacturing, catering & real estate, real estate and tax shelters shyster, packaging materials, car dealerships, heir to the Johnson & Johnson company, movie theater chain, building shopping malls, co-founding Microsoft, Wal-Mart heir, marketing and advertising and of course, inheriting wealth (and the team) from a rich parent
Owners make decisions based on their experience and expertise. It's not usually football. The smart ones (sometimes) hire good football people and give them the freedom to make decisions based on what is best for the team with football expertise in mind. Mr Pegula has (after stumbling a bit the first few years) has mostly followed this method to extremely good success.
So, YES. Green Bay has YEARS and YEARS of "institutional" knowledge, experience and expertise grounded in FOOTBALL. NFL owners have "institutional" knowledge, experience and expertise on how to make money with various business as detailed above.
Owners are impatient and make sometimes rash decisions not based on what is the smartest move for football success.
So, YES. Green Bay DOES HAVE "institutional success" grounded and passed on by years of putting football minds in control and not owners that have made money in other ventures.
