Per the Instagram page sogfootball, Gale Sayers is the 4th best returner in NFL history. I think that is a fair statement. Sayers was a great, all-around player that struck fear in his opponent's head.
Here are his return stats:
Sayers was a 5x All-Pro, 2� NFL rushing yards leader, NFL Comeback Player of the Year, NFL Offensive Rookie of the Year.
His career was, unfortunately, cut short due to many injuries, but for the 7 years he played in Chicago, he was one of the most dominant players this game has ever seen.
Sayers died in September 2020 and he would have turned 79 yesterday.
