Landry played the majority of his NFL career with the Lions from 1968, when he was drafted with the No. 11 overall pick, until 1978. He was traded to the Colts and played three more years before moving on to the USFL.

He returned to the NFL in 1984, where he played one more season with the Chicago Bears before officially retiring.

Landry threw for 16,052 yards and 98 touchdowns, but he was known best as one of the top running quarterbacks in the league with 2,600 yards on the ground and 21 touchdowns. 

He was named the NFL's Comeback Player of the Year in 1976. Landry eventually made his return to the Lions as a coach in 1995 and was the Bears’ offensive coordinator when they won the Super Bowl in 1986. 

Landry also left his mark at UMass as one of the program’s greatest quarterbacks. He led the team in both rushing and scoring for two seasons and led the university in two Yankee Conference Bean Pot wins.

He was inducted into the UMass Athletics Hall of Fame in 1980.
