Former Titans star running back Chris Johnson remains a free agent after being released by the team.
Tom E. Curran joins Mike Giardi on SportsNet Central to discuss if the running back position has become devalued in the NFL.
"The reason is, you can do it with a guy who is undrafted as the Patriots did with BenJarvus Green-Ellis and Danny Woodhead, you can do it with a number of guys. So why spend six or seven million dollars on one guy?" explained Curran, "There's so many ways to address moving the football. I think the days of the 'bell cow' are dead."
