‘Edwards was expendable in part because of his hefty contract and also because he no longer fits in the Bills defensive scheme after the team made the switch to a 4-3 alignment this offseason. After spending the past two seasons in Buffalo starting at defensive end, he was relegated to a backup role at tackle behind Marcell Dareus and Kyle Williams. Edwards had two years left on the $18 million contract, and scheduled to make a $4.1 million base salary this season.’
