It feels like a perpetual cycle among the fans where the last failed contracts (i.e. Tyreek, Chubb, Tua) are bashed as obviously doomed from the start and idiotic, while the new contracts (e.g. Achane, Brewer) are praised as smart and forward-thinking.
Personally, I felt a lot more optimistic about handing out big contracts for players on a team expected to contend than I do about handing out big contracts for players on a team expected to pick first in the next draft. But it's not my money, so...
The contracts of Achane & Brewer aren't going to cripple the cap (and the rest of the team) as much of those as Tyreek, Chubb, Tua (plus you can add Armstead and Ramsey - and potentially Waddle if it was renegotiated like those others into more major guaranteed money - into that bunch). That says a lot given how cap-fucked we are this season (and a good chunk of next season too).
Grier took a major craps shoot on most of those contracts to win up big in 2023, and it all went bad immediately afterward. The Tua Contract was the Point-Seven-Out at the end of it.
Or to put it more bluntly... Achane & Brewer's contracts are not going to land us in salary cap hell. Those previous mentioned contracts have us slow basting in a temperature that resembles something close to the surface temperature of the planet Venus with the added bonus of sulphuric acid rain.
