That's the question Jerry needs to ask himself.
Jerry takes a lot of crap, and some of it's justified. But even with him as GM and McClay there helping, they tend to put together some talented teams, at least talented enough to win. Other than a random year or there, they are rarely awful and rarely awful for a long stretch. They are good. Have not been great since the mid 90s.
Now we can keep McCarthy and Dak and probably be good again next year. Certainly not a SB contender but likely good enough to get a WC spot and depending on what Philly does, maybe contend for another divisional title. If that's what Jerry is OK with, then fine.
But to be great, you need to bite the bullet and pull the plug on both Dak and McCarthy. You have to be willing to eat a year or two of mediocrity to be great.
I don't think Jerry is willing to do that. I think Jerry believes that just being good is good enough and that eventually luck will kick in and we'll make a run. Problem is, he's had no luck for nearly 3 decades.
