Most of Miami's offense, outside of Tua in 2025, is locked up, the defense is where they will finagle the money with the cap.
Also, you are really banking on teams falling apart and the Pats being good because of the cap. Do you remember a couple years ago when the Pats had all that cap space? Yea, here is what they did:
Threw it all away for the most part and got worse each season after.
And for the cap killing teams? Teams always figure it out that are contending, Saints, Cowboys, Eagles, and Rams were always in a bad spot and find a way to restructure until they want to the bottom fall off and need to rebuild, ala Rams last year.
