The Eagles have no desire to move the 5'10/180 Boykin out of his slot position, a role he excelled in last season. Outside corners Cary Williams and Bradley Fletcher will be backed up by new additions Nolan Carroll and Jaylen Watkins. Boykin was PFF's No. 2 corner in terms of coverage in 2013, behind only Indy's Vontae Davis.
