Over the years, the New England Patriots have had plenty of success with undrafted free agents. No fewer than nine players on the current 53-man roster — including starting center David Andrews and special teams standout Brandon King — did not hear their names called on draft day but were subsequently signed by the Patriots. Before them, contributors like Adam Vinatieri, Matt Chatham and Randall Gay also joined the team this way.
The gold standard when it comes to undrafted rookie success, however, remains Malcolm Butler.
