If Cobb leaves, Boykin could reemerge. In the 10 games that he replaced Cobb in 2013, he had 46 receptions for 600+ yards. When Cobb returned at the end of 2013 and all of 2014, Boykin disappeared. It may just be that Boykin is a good slot receiver, but not good enough to beat starting CB's when lined up outside. Boykin is only 25 years old, and there's no reason why a guy who was a legit #3 in 2013 would be finished.
