The New England Patriots are in Foxboro, MA and preparing to defend their Super Bowl 49 championship. As OTAs (Organized Team Activities) finally return the players on the field at Gillette Stadium–even if it is without pads or contact–it signals it is finally time to turn to some big questions about the defense. The Patriots released all four of their top four cornerbacks (Darrelle Revis, Brandon Browner, Alfonzo Dennard, and Kyle Arrington) freeing up $45 million in cap space but weakening their secondary.
