I idolized Rocket Ismail, but Gordon is the most underrated college football player of all time. He'll get his due respect in time, but we've whiffed on him as an audience. His 2014 season is basically a Barry Sanders season, plus he averaged over 8 yards per carry outside of that season for his college career. It's not that he finished 2nd to Mariota for the Heisman, it's that Mariota won in a colossal landslide that shows me Gordon is underrated.
For all his exploits, Ismail only scored 15 TDs his entire career. The threat of him was bigger than the actual production. Gordon had more than that in his first 7 games of his SR season.
