Pettigrew was a 2nd-round pick in 1966, and started 10 games at right defensive end in each of his first 2 seasons.
In 1968 the Birds revamped their defensive line, putting 1968 #1 pick Tim Rossovich at LE and 2nd-year man Mel Tom at RE. Pettigrew moved to right DT, where he stayed for the next few years.
Starting all 14 games in 1968, he was limited to 6 starts in 1969, missing 7 games due to injury.
In 1970 he again started every game at RDT, but the next 2 seasons found him mostly riding the bench, behind regulars Don Hultz, Ernie Calloway (in '71), and Houston Antwine ('72), only starting 6 of his 13 games in '71 and 2 of his 13 games in '72.
Gary was back in the lineup in 1973, starting 12 of his 14 games, but this time at left tackle.
After 4 games (no starts) in 1974, he was traded to the Giants, and retired after the season.
