As an NFL head coach, Glanville was more famous for his antics and brash, outspoken personality than for his success on the field (his career record is 63-73). While coaching the Falcons, he regularly challenged and mocked opposing teams players on television and in interviews. He was also famous for often leaving tickets at will-call for the late Elvis Presley, wearing all black to be easily recognized by his players, and driving replicas of vehicles driven by James Dean.
When Brett Favre was selected in the second round of the 1991 NFL Draft by Atlanta, Glanville did not approve and said it would take a plane crash for him to put Favre into a game. Favre only threw four passes during his one season with Atlanta. After leaving Atlanta for Green Bay, Favre would go on to play 19 seasons, starting every game from September 20, 1992, to December 5, 2010, and becoming the first NFL player to win three AP MVP awards, a feat matched only once since. He would also appear in two Super Bowls, winning Super Bowl XXXI.
On February 28, 2007, he accepted the head coaching position at Portland State University (PSU), his first college head coaching job. Glanville, who replaced Tim Walsh, was PSU's 12th head coach in the history of the program. He resigned this position with the support of the university on November 17, 2009, with an overall record of 9–24 during his tenure.
Jerry also had a brief career as the Owner/Driver of a black #81 Craftsman Truck Series from 1995 thru 1999, with a best finish of 14th four times. He finished 18th in the points in 1995 as his best points position of his career.
Jerry appeared among the hosts of the pregame shows for Cartoon Network's annual Super Bowl parodies, The Big Game, from 1999 through 2001 - Tweety VS Sylvester in 1999, Wile E. Coyote VS Road Runner in 2000, and Bugs Bunny VS Daffy Duck in 2001. In the pregame picks for these games, he always picked the character who was not likely to win; surprisingly, in the Bugs VS Daffy game, he was correct in predicting that Daffy would win.
