The New England Patriots have regularly experienced more success stories with undrafted free agents than most NFL teams. New England head coach Bill Belichick can take most of the credit for that because of his uncanny due diligence. Belichick’s respect for players flying under the radar is unmatched. That is why so many succeed under his tutelage.
Cornerback Malcolm Butler is the most obvious recent example of an undrafted player success story after he was signed as a free agent in 2014. Butler turned into a successful starter in his second season out of West Alabama.
