The Facts: Woodhead, a running back who arrived in the NFL as an undrafted rookie in 2008 and lasted a decade in the league, has decided to call it a career. The 33-year-old Woodhead wrote on Instagram that he is retiring.

Diehards Line:Woodhead became the best player in Dviision II football, twice winning the Harlon Hill Trophy, the Heisman of Division II. Despite that career, Woodhead was not invited to the Scouting Combine and wasn’t drafted, but he signed with the Jets as an undrafted free agent. After spending his rookie year on injured reserve, he put on a show in the preseason of 2009, rushing for 158 yards in one preseason game. That was enough to earn him a spot on the practice squad, and he was eventually called up to the active roster. After the Jets cut him in 2010 the Patriots picked him up, and he flourished in New England. Woodhead had 97 carries for 547 yards and another 34 catches for 379 yards in his first year with the Patriots. He would spend three years with the Patriots before signing with the Chargers, spend four years in San Diego, and finish his career last year in Baltimore.
