Hailing from Duke University, McAfee arrived in the league with the Chicago Bears in 1940. Standing at a sturdy 6 feet and weighing 200 pounds, he possessed a unique blend of power and speed. While primarily a running back, McAfee's skillset extended beyond the backfield. He excelled as a kick returner, a punter, and even played some defense. This versatility made him a valuable asset for the Bears, allowing them to utilize him in various offensive and defensive schemes.

McAfee's most significant contribution lies in his innovative running style. Unlike the typical straight-ahead rushers of the era, he incorporated lateral movements and jukes into his game, confusing defenders and creating space. His ability to catch passes out of the backfield further expanded his offensive repertoire, a concept that would become commonplace in future decades.

McAfee's career was tragically cut short after just four seasons due to a serious knee injury sustained during World War II. Despite the brevity of his playing time, his impact is undeniable. He is credited with helping to redefine the role of the running back, showcasing the effectiveness of a player who could not only run the ball with power but also contribute in the passing game and on special teams.

The legendary back that played for Duke University and the Chicago Bears was so good at both levels that he is inducted into the College Football Hall of Fame and the Pro Football Hall of Fame.
