‘At one point in his career, Harvin was among the most dynamic players in the NFL but injuries and migraines caused him to miss a lot of time on the field. The wide receiver played with the Bills from 2015-2016, but only appeared in seven games over that time. A knee injury ended Harvin’s 2015 campaign (19-218-1 in five games). Harvin would retire in April of 2016, but returned to the Bills that November. He lasted two games before migraines ended his comeback.’
