I was watching ESPN this morning before Gameday and notice the topic of "touching traditions". This was an interesting topic because I know many schools have some sort of tradition of football players touching something as they run onto the field. Alabama players rub a bronze bust of coach Bryant with his houndstooth hat before they run through the tunnel and onto the field. Anyways, the segment showed that Nebraska football players touch a horseshoe hanging above a door as they exit the locker room and go through the tunnel. I was just wondering the significance of this horseshoe since I was unaware of it until this morning. Thanks in advance.
