We won't anyways. If Ben retires at the end of the year they'll give Mason at least one year based on the week 17 game.
Also that cap number being over is based on a $175 mil cap. There's projections that say it's gonna end up at $198 mil.
Additionally is Ben retires ($19mil in savings), I would fully expect Pouncey to retire ($8mil in cap savings), McDonald to be cut ($8mil savings), and Haden to be cut or take a paycut/extension ($13mil savings if cut, $8ish if taking a pay cut). All of that together gets us to $38mil in cap savings and $17mil under the cap without any restructures or extensions that lower the 2021 cap hit.
