The Buffalo Bills carried over just under $6 million in salary cap space from 2020 according to Field Yates of ESPN. That means their salary cap space will be that much higher than the official league-announced cap number whenever that becomes official. Buffalo’s total of $5,876,959 is 21st in the NFL in terms of carryover.
Buffalo currently has $187,510,612 in salary cap commitments in 2021. The NFL’s salary cap won’t be lower than $180 million, so adding the $5.8+ million means Buffalo will still be over the salary cap without making roster moves or contract restructures.
