I would argue that the cap management techniques the Saints are using are a problem and if you utilize this technique then it better result in a super bowl or you should be fired. Rams and Bucs are good examples of using it correctly then right sizing the cap immediately and getting out to start the rebuild process again.
Teams like the Dolphins, Chargers and Bills are teams that are going to set themselves back with nothing to show for it.
The Chargers have a ton of flexibility so they'll be fine. They may part with some good players via trade, but they can get assets back for a lot of those guys clearing a lot of cap. That is something Harbaugh might want to do regardless.
The Bills do have some challenges, but the biggest contract they have is also their best player and there is room to absorb some of his salary into bonuses in 2027/2028 when he is only 31 or 32 years old. That knocks their deficit in half without the use of void years. They can drop another $6.7 million by cutting Von Miller and from there they can get the rest of the way pretty easily with cuts/trades or restructures. That is without touching their $30.8 million in cap space in 2025.
The Dolphins are a bit tougher. They did kind of go all in and came up short. If they like Tua and want to extend him, then they can take care of a bit right there. The rest I would assume they would push into 2025 where they are $58 million under the cap.
As it stands today, the Saints are the only team that is already over the cap for 2025 with nearly $40 million to clear. But I keep hearing we're not the only ones that do it this way.
