Ja’Marr Chase signs 4-year $161M extension ; Tee Higgins signs 4-year, $115M extension

They have the cap space, next year they have over 140m in cap space but also have 40 less players under contract. This has not been updated on over the cap yet for those increases to the WR room. Either way they need cheaper talent in other places.
They can definitely manipulate the cap to make things work to fill the roster, the problem comes with Mike Brown who is notoriously cheap. Will he be willing to fork over the millions in signing bonuses every year it will require to manipulate the cap?
