Bills re-signed CB Leodis McKelvin to a four-year, $20 million contract.
McKelvin was the most explosive return specialist in football last season -- Jacoby Jones included -- but the money here is surprising and may indicate the Bills envision McKelvin as a 2013 defensive contributor. He's long struggled in pass coverage and with his ball skills. Turning 28 before the season, McKelvin will probably compete with Aaron Williams to start at left corner opposite RCB Stephon Gilmore. The LCB position figures to remain an exploitable weakness if Mario Williams and Mark Anderson can't generate better pass rush.
