NEEDS: More salary cap space. The salary cap-squeezed Buffalo Bills have little money to work with even after GM Brandon Beane restructured the contracts of Josh Allen and Von Miller to free up more than $30 million of cap room. That still leaves the Bills little breathing room to begin filling numerous needs, which will include the likelihood of having to replace long-time defensive fixtures Edmunds and Poyer. The process began Sunday, with linebacker Matt Milano agreeing to sign a two-year contract extension in a move that freed up $6 million against the cap. Edmunds’ expected departure – he already has agreed to a deal with Chicago – leaves a huge hole in the middle of Buffalo’s defense, while Poyer was part of a veteran defensive secondary that included starters Micah Hyde and Tre’Davious White. The Bills could use more experienced depth at receiver after Gabe Davis failed to establish himself at the No. 2 role opposite Stefon Diggs. Both lines are again in transition, though Saffold and Phillips expressed interest in returning under relatively modest contracts.

AVAILABLE SALARY CAP SPACE (approximately): $12 million.
