As one of the most memorable sports icons of the 20th century, it should not surprise anyone that Walter Payton inspired millions with his strength, agility and determination on and off the field. However, it may surprise you to know that today, he still makes a positive impact on the world around him. He is an avid supporter of cancer research and has encouraged many other athletes to follow in his footsteps. This ensures that his NFL football career will not only remain one of the greatest in football history, but that his legend will live on for many years to come.
