43. Devin McCourty, S, Patriots
Bill Belichick has shuffled through a long list of players in the secondary, some of them superstars (Darrelle Revis) and others of the diamond-in-the-rough persuasion (Malcolm Butler). The one constant since 2010 has been McCourty, whose value only has grown since the Patriots slid him to safety midway through the ’12 season. He has the requisite capabilities to handle a variety of roles. He tends to be at his best, though, when dropping deep in coverage and providing the support New England’s occasionally ragtag collection of cornerbacks needs. Belichick clearly trusts his scheme, hence his revolving door at CB. But McCourty’s development as a safety over the past few seasons is one of the main reasons why that scheme works.
