A year ago, the Buffalo Bills' new regime made a handful of heady moves necessary to complement the team's "building through the draft" mentality. None of the free-agent signings took the world by storm at the time, but players like Leodis McKelvin, Manny Lawson and Alan Branch were valuable assets both last season and moving forward.

The Bills know their future relies on drafting well at the top of the draft, but crafty moves in free agency will be just as important to move them closer to their first division title in well over a decade.

For some positions, the solution is as simple as re-signing a guy who is already familiar with the schemes, while other spots will need some fresh blood.

Over the next few slides, we will take a look positions that need attention in free agency and others that should be just fine moving forward.
