According to Pro Football Talk's Mike Florio, Brown will receive a little over $50.1 million through the 2021 season, up from $38.9 million under the deal's original terms. Brown's guaranteed money also climbed from zero to $30.1 million, per Florio.
Beckham signed a five-year, $90 million extension with the Giants last August, but he has good reason to either seek a new deal or renegotiate the particulars of his current contract.
While he has more than $72.7 million left on his contract, only $16.7 million of that is guaranteed salary, per Over the Cap. That guaranteed money is entirely limited to the 2019 season as well, so Beckham has little in the way of long-term security.
The Browns made a big investment in Beckham by giving up so much for him in Tuesday's trade. However, they would have few hurdles if they wanted to release him at any point beyond this coming season.
To avoid any friction with their newest star, the Browns might agree to restructure Beckham's contract. Adding a few million dollars and increasing his guarantees wouldn't significantly alter their financial flexibility going forward—at least much more than adding his existing contract to the payroll did.
