Glenn burst onto the scene at Ohio State, where he caught 64 passes and scored 17 touchdowns in 1995. That year, he won the Fred Bilentikoff Award, given to the nation's top wide receiver.
Glenn was drafted seventh overall by the New England in 1996. He played for the Patriots for six seasons, playing in the Super Bowl during his rookie season.
Glenn was also under contract with the Patriots during the team's first Super Bowl victory in 2001, though a failed drug test and a domestic dispute arrest led coach Bill Bellichick to deactivate him from the roster. He did not receive a Super Bowl ring following the Patriots' win.
