Yeah, no teams should have that kind of cap space. That is the sign of a reset gone entirely wrong.
Let's look at the successful teams though. There are five 2024 playoff teams that have are between $5m and $20m in cap space in 2025 (Eagles, Ravens, Bucs, Chiefs and Texans). Only one playoff team has negative cap space, the Bills. All of the rest have $40m+ in 2025 cap space.
Of the non playoff teams with negative cap, Seattle and Atlanta can restructure a single player each and be under tomorrow. The Saints and the Browns are the only bad teams with super high cap numbers and the Browns have the excuse of signing the worst contract in NFL history and are $20m less in the hole than the Saints.
I think the merits, or lack thereof, the Saints cap plan are evident regardless if a few people want to continue to defend them.
