The Browns paid Keenum, 34, his $1 million roster bonus due on Friday, and reworked his deal to execute the deal with the Bills. In the third and final year of his Browns contract, Keenum had a base salary of $6.1 million, his prorated signing bonus of $1.33 million, and the $1 million roster bonus for a cap hit of about $8.4 million for 2022.
But they restructured to make it more pallatible for Buffalo, and essentially purchased the seventh-round pick for $1 million.
