'By releasing Williams, the Bills will save $1.775 million against the cap. They could also designate Williams as a post-June 1 cut, which would save them $4.2 million against the 2017 cap but give them a $2.4 million charge on the 2018 salary cap. If the Bills decide to designate Williams as a post-June 1 cut, they won't get the $4.2 million in cap relief until after June 1.'
