The Facts: Felton, who helped pave the way for running back Adrian Peterson during his record-setting 2012 season, has opted out of the final year of his contract with the Vikings and will become an unrestricted free agent.

Diehards Line: Felton joined the Vikings in 2012 and was Peterson’s lead blocker as the star back rushed for 2,097 yards that season and was named league MVP. Felton joined Peterson at the Pro Bowl after the season and scored a rushing touchdown. Felton had a significant role again in 2013, but that changed this past season when first-year HC Mike Zimmer hired Norv Turner as offensive coordinator. Turner has used fullbacks sparingly in recent seasons, and that trend continued with Felton. Felton played just 16.6 percent of the offensive snaps, and his role diminished further down the stretch as the Vikings more often used a spread attack with Peterson suspended and rookie quarterback Teddy Bridgewater being forced to shoulder the offense. In his three seasons in Minnesota, Felton played 45 games, starting 19 of them, and added 27 yards on four carries as a rusher.
