They’re in rough shape because the cap went backwards $20M, which they likely structured cap hits assuming a rising cap. The teams that weren’t fucked by the cap were teams that were purposely rebuilding and had shes salaries like NE or teams or never use their cap space fully, like JAX. They also assumed they would be doing another December restructure with Rodgers, which always eases the burden. There’s space to push Rodgers money into ‘22/‘23.
Until the league reigns in dummy years, there’s no reason not to give Adams a 3 year, $90M deal with 7 additional dummy years or whatever. Its what KC did with Mahomes essentially. Pay a manageable amount over 3 years and then keep him on the books for a while at a low cost. Cap will keep going up.
