3. Herschel Walker
Walker is the best-known NFL player to make the move to MMA. Entering his professional career following one of the most decorated college football careers in history -- a run that included a Heisman Trophy and national championship at the University of Georgia -- Walker played in the now-defunct United States Football League before spending 11 seasons as a running back and kick returner with four different NFL teams. As an NFL pro, Walker racked up more than 8,000 yards and scored 82 touchdowns. He still ranks ninth on the league’s all-time list for all-purpose yards with 18,168.
With no fights since 2011, it seems Walker’s fighting career has run its course, but if his two bouts were any indication, age will not be a determining factor in whether or not he thinks he can compete. With former Strikeforce CEO Scott Coker now fronting the Bellator MMA promotion, never say never.
