I'm about to be 46, I've been a fan since my Dad got me a Richard Todd jersey which I wore in my 1st grade class photo.
In that time, the same consistent element of this organization is the ownership and their true lack of care in what the organization puts on the field. I would go so far to say that Sonny Werblin and the Werblin group were the last set of owners to make a concerted effort to win. Hess could have cared less. The Johnson's could care less. Every year their books are in the black and no matter the disaster, every year the fans, the season tickets, the advertising, and the PSLs come back.
Owning the Jets is a cute little asterisk next to their name for the Johnson's to boast about on their Yacht when they're hosting cocktail parties. At the end of the day, this entire ownership group could care less about winning and what's on the field. The books are in the black ....because owning a NFL franchise is a license to print money. I've said it for years. Show me the last NFL franchise to bleed money?
The culture within the organization starts from the top and the culture has been all about apathy through both the Hess and Johnson Administrations. Terrible financial decisions + Terrible personnel decisions = The product on the field. The product on the field has been garbage for a majority of the Hess and Johnson year and it will never change.
