Byrd's signing bigger than Revis'

NFL history affords many instances of a cornerback joining a team and vaulting it to a championship. Herb Adderley, Mike Haynes and Deion Sanders all bolstered their already strong Hall of Fame cases by doing so, adding Super Bowl rings to their collections in the process.

This type of cornerback historical background is part of the reason the New England Patriots' signing of Darrelle Revis has been met with plenty of praise. However, that acquisition might not even be the most impactful offseason secondary signing in the NFL, as the metrics and game tape show that the New Orleans Saints' signing of free safety Jairus Byrd to a six-year, $54 million deal will have a bigger impact.
