Mike McCarthy will be back in 2024

Yes, it is a different discussion when your team is a 10+ playoff team like Dallas, Philly, or Pitt. However, at a certain point, you do have to evaluate whether or not they're achieving the ultimate goal or being a championship-caliber team. Hence, you do let Any Reid or Bill Cowher go after a certain point.
If this were 10-15 years ago, there's a decent chance Jerry wouldve fired McCarthy and gone after HC's like Belicheck or Harbaugh, gave them some vague, illusory promises and guarantees about greater personnel decision-making that Jones wouldn't unlikely cede or give up because he's such a paranoid, control freak that is determined to win another Super Bowl according to this stubborn ownership philosophy of doing it his way.

Jones knows and recognizes his impending mortality, he realizes he likely won't be alive 10 years from now, and another HC change/turnover, massive overhaul of assistant coaches that accompany it, so he doesn't want to blow it up.
