A breakdown of the initial wave of free agency for the Buffalo Bills:
Overall grade: B-plus. Of the $50 million the Bills guaranteed to players they signed or re-signed, $43 million was paid to players who are 28 or younger and reaching free agency for the first time. Although the positions and players on which the Bills spent the money can be debated, it was an ideal approach that could help address what was an aging roster in 2017.
Most significant signing: In terms of financial investment, the headline signing of free agency was defensive tackle Star Lotulelei.
