Christian McCaffrey, Robbed of Heisman Trophy?

In the CBS article about Ed McCaffrey speaking on his son and his accomplishments at Stanford, a light is shed on how the white running back has always lived in the shadows of the more traditional black running back. When Christian was asked when the last time a white running back won the Heisman, he had no idea that the last man to win it was John Capaletti...in 1973. The Heisman winner is supposed to be represented by the best all around and most versatile college football player in the nation. Although Christian McCaffrey has the best numbers by far out of all the running backs in CFB, he was still stripped of the Heisman Trophy, and lost to Derrick Henry, a black running back from the University of Alabama. Henry was not nearly as versatile as McCaffrey and did not match the stats he put up in that single-season. Moving into the NFL combine, a series of drills to showcase your skills for NFL scouts, Christian McCaffrey shined as one of the greatest and most well-rounded running backs heading into the draft. However, when the NFL draft came around, he was the second running back selected in the draft, behind Leonard Fournette, a black running back out of Louisiana State University. Although McCaffrey had a way better performance at the combine, Fournette was selected over him. So, I wanted to ask, do you think that the white running backs are living the shadows of the black running backs? Why do you think that is?
