Winning in the 4th quarter is only rarely about talent or playmaking. It more often about confidence, mental-fortitude, understanding your system, and making in-game counter moves to shore up weaknesses and expose them in your opponent. 

 

Most of those are instilled or worked on by coaching staff. Rare players are leaders that can lightning rods to a team to do that, but more often you cannot predict a player's response because many have not had hard obstacles or difficulties that they will face coming to the NFL. That is why so many draft picks fail, and why players can change teams and then all of sudden "get it". That is also why the NFL has a high percentage of teams that go from worst-to-first in their divisions. Those teams are not severely lacking in talent. They are lacking in confidence and preparation and that can be changed.

 

That is why even most of even the "best" GM's/coaches that everyone would sell a kidney to bring to the Jaguars do not get to the Super Bowl or even the playofsf every year, and streaks of consistently just making the playoffs like the Patriots are outliers. 

 

I'm not saying that no matter what that the Jags should keep Dave Caldwell. He is an average GM. But it also means that you don't just get rid of him unless you have a great option with whom to replace him right now.
