Herschel Walker is the greatest running back in college football history. The entire Georgia football fanbase knows this. Many people outside the fan base know this as well, but if you spend enough time on sports news websites, channels, blogs and social media, you’ll see cases made for several other running backs.
Bo Jackson and Barry Sanders are popular names in the “greatest running back” discussion. You might hear or see someone bring up Archie Griffin, OJ Simpson or Ron Dayne. But there’s no case for those players, there’s no case for anyone else.
