Alvin Kent Nix (born March 12, 1944 in Corpus Christi, Texas) is a former professional American football quarterback in the National Football League. Nix played football collegiately at Texas Christian University (TCU). He is the son of Emery Nix, New York Giants quarterback who played for the New York Giants in 1943 and 1946. 
Texas Christian quarterback
Nix helped TCU to an upset of Baylor University in October 1964. He passed 4 yards to Joe Ball for the first score in a 17-14 win at Fort Worth, Texas. He led the Horned Frogs on four long scoring drives as a senior quarterback to defeat Baylor in Waco, Texas, the following October. Nix hit on five consecutive passes during a 79-yard drive for a touchdown, in the second quarter. TCU won on a field goal by Bruce Alford in the third period. Nix tied a Southwest Conference record with 4 touchdown passes of 31, 24, 12, and 15 yards, versus Rice University, in November 1965. He also scored on a one-yard plunge to give Texas Christian a 42-14 halftime lead. His first two touchdown passes came in the first ninety-three seconds following Rice fumbles.  Nix was bothered for much of his collegiate career by a knee injury. While at TCU, he was a member of Delta Tau Delta fraternity.
Green Bay Packers (1966)
Nix was cut by the Green Bay Packers on August 2, 1966. He passed through waivers but was retained on the Packers' taxi squad for the remainder of the 1966 season. After clearing waivers Nix became a free agent.
Pittsburgh Steelers (1967 - 1969)
He got his first chance to play in the NFL with the Pittsburgh Steelers in September 1967. The Steelers regular quarterback, Bill Nelsen, had an injury to his right knee. Nix was the only other quarterback on the roster. He made his debut against the Philadelphia Eagles. Nix connected on an 18-yard pass to J.R. Wilburn to tie the score, 24-24, midway through the fourth quarter. The Steelers lost in Philadelphia, Pennsylvania, 34-24. Nix completed 23 of 34 passes against the Cleveland Browns for 218 yards and one touchdown, in October 1967. Split end Dick Compton caught ten of his passes. Nix hit rookie Steelers' running back, Don Shy, for a 27-yard touchdown in a loss to the Giants at Pittsburgh, on October 15.
Tom Landry called Nix the best rookie quarterback he had seen in ten years. Nix guided the Steelers to a 24-14 triumph against the Detroit Lions on December 3. He handed off to Shy for two one-yard touchdowns to cap drives of 80 and 64 yards in the first and second quarters. He fooled the Lions' defense by passing often on first and second down. Most significantly Nix found swift J.R. Wilburn for a 67-yard touchdown with 1:49 remaining in the second quarter. He led the Steelers on a 78-yard drive, completed by a Nix to John Hilton 3-yard touchdown pass, which gave Pittsburgh a temporary 10-9 lead against the Washington Redskins. During the drive at Pittsburgh on December 10, Wilburn caught four passes for fifty-five yards.
Chicago Bears (1970 - 1971)
Nix signed with the Chicago Bears and spent the 1970 season on the taxi squad. He rallied the Bears in the fourth quarter for a second straight week, coming from behind to upset the Vikings, 20-17, in September 1971. He threw touchdown passes of 36 and 26 yards to Dick Gordon in Minneapolis. The latter pass found Gordon in the end zone with 1:42 remaining in the game. Bears starting quarterback, Jack Concannon, was knocked out of the game on a hit by Carl Eller.
Nix started his first game since 1968 in a 35-14 beating of the New Orleans Saints at Soldier Field. He threw touchdown passes of 25 and 35 yards to Bob Wallace and Gordon. Overall, he completed 14 of 24 passes for 242 yards.
The Bears waived Nix on September 13, 1972. In March 1974 Nix filed suit against the Bears, charging they had misdiagnosed a November 1971 hand injury as a sprained wrist. He asked for more than $10,000. Nix had continued playing following the preliminary diagnosis. In his lawsuit he claimed that the injury was aggravated. A later diagnosis stated that the injury was a rupture of both tendons of the index finger of the right hand.
