Robert Lee "Bullet Bob" Hayes (December 20, 1942 – September 18, 2002) was an Olympic sprinter turned American football wide receiver in the National Football League for the Dallas Cowboys (for 11 seasons). An American track and field athlete, he was a two-sport stand-out in college in both track and football at Florida A&M University. He has one of the top 100 meter times by NFL players. Hayes was enshrined in the Dallas Cowboys Ring of Honor in 2001 and was selected for induction in the Pro Football Hall of Fame in January 2009. He was officially inducted in Canton, Ohio on August 8, 2009. Hayes is the second Olympic gold medalist to be inducted to the Pro Football Hall of Fame, after Jim Thorpe. He currently holds the world record for the 70-yard dash (with a time of 6.9 seconds). He also is tied for the world's second fastest time in the 60-yard dash.
He was once considered the "world's fastest human" by virtue of his multiple world records in the 60-yard, 100-yard, 220-yard, and Olympic 100-meter dashes. Hayes tied the world record to win the 100 meters, then anchored the U.S. 4x100-meter relay team that broke the world record. Hayes is the only athlete to win both an Olympic gold medal and a Super Bowl ring. He was inducted into the United States Olympic Hall of Fame.
