Hagan also played for the New York Giants, Buffalo Bills, Oakland Raiders, and Tennessee Titans.
He caught 78 passes for a school record 1020 yards and five touchdowns as a senior, while adding nine interceptions on defense.
Hagan was recruited to Arizona State University by head coach Dirk Koetter whom he played under for two years.
He surpassed 1,000 yards receiving in each of his final three years as a Sun Devil, leading the team each time.
Despite his great career at ASU, Hagan had a poor showing during the Senior Bowl practices by dropping passes, which many predicted would damage his stock in the upcoming draft.
His problems with dropped passes continued throughout much of the season, and he failed to distinguish himself as a legitimate receiving threat.
These drops, combined with the struggles of the Dolphins offense as a whole, resulted in a largely uneventful rookie campaign for Hagan.
The lone score came in an October 22 loss to the Green Bay Packers on a pass from Joey Harrington.
Hagan was signed by the New York Giants on December 16, 2008, after running back Reuben Droughns was placed on injured reserve.
Hagan earned a Bachelor of Science degree in justice studies while at Arizona State University.
