1972 Topps football card of former NFL quarterback Bill Nelsen, who played 10 seasons in the league for the Pittsburgh Steelers and Cleveland Browns. He was known mostly for his toughness as he lasted as long as he did despite suffering numerous serious knee injuries. He had limited success in 5 years with a lowly Steeler club, but after being traded to the Browns he took over as the starter when injuries sidelined Frank Ryan and guided the Cleveland club to the postseason 3 times. He served as an assistant coach with various NFL clubs after retiring as a player.
