Overview
William Keith Nelsen (January 29, 1941 – April 11, 2019) was an American professional football player who was a quarterback in the National Football League (NFL). He played college football for the University of Southern California before playing professionally for both the Pittsburgh Steelers and Cleveland Browns. He was known for his leadership and willingness to play with pain, enduring a series of knee injuries during the course of his career. He later served as an assistant coach with four NFL teams.
College career
After playing one season of community college ball at Cerritos College in California, Nelsen moved on to USC, where he was a key player during his first two seasons, leading the squad in total offense in both 1960 and 1961. In 1962, he split time at the position with Pete Beathard, helping the team capture the national championship.
Professional career
Nelsen was drafted in the 10th round of the 1963 NFL Draft by the Steelers, but saw limited action during his first two seasons. In 1965, new head coach Mike Nixon gave Nelsen the starting job. However, the struggling team finished 2-12, offering him little help, with Nelsen throwing for eight touchdowns, in addition to 17 interceptions. In the November 14, 1965 game against the Dallas Cowboys, Nelsen suffered a knee injury that plagued him the remainder of that year; he underwent surgery after the season.
The following season, Nelsen suffered a knee injury against the Detroit Lions in the season's second game. Originally scheduled to be out of the lineup for six weeks, Nelsen did not return until the season's 12th week. The limited time on the field allowed him to set a league record for fewest interceptions (100 minimum passes) with just one on the campaign. In the season finale on December 18, he completed his final 11 passes to defeat the expansion Atlanta Falcons.
