Whilst I agree that the teams use the CAP differently I would say that the CAP has to be paid as some point, with us 2022 by accident, rather than design ( Gregory) is where we reset.
The Rams arent using the CAP as a speed bump....The Reaper's already knocking on their door. Next season they will wont have an O-Line and a D-Line that'll be Donald, JAG, JAG, JAG, already overspent on the predicted CAP level and with a 2023 draft with highest picks...2nd/3rd and 6th Rd.
It gets worse: 2024, they are still over CAP (what they defer from 2023)....still no O-Line and D-Line.
2025 - 44M just in void money. That could rise to minimum guranteed Dead Money of $100m or even $120m depending on what they do with Stafford/Kupp/Wagner.... but that would be a team without a QB and Donald.
The Chiefs make hard decisions to strengthen areas whilst accepting they have to surrender stars to facilitate that transition (Plus = O-Line rebuild , Sacrifice = Tyreek Hill).
