Joseph Cassidy Glenn (born March 7, 1949) is an American former college football player and coach.

[1] He was named head coach on December 5, 2011, after the school's athletic director, David Sayler, fired Ed Meierkort.

After Doane, Glenn made his first stint at the University of Montana as a quarterbacks and wide receivers coach and offensive coordinator from 1980 to 1985.

In 2001, the Grizzlies won the NCAA Division I-AA Football Championship, defeating Furman in the title game.

The year before, the Grizzlies finished as the NCAA Division I-AA runner-up, losing to Georgia Southern in the championship game.

The Cowboys won their final game against UNLV, moving them to a 6–6 record, and making them bowl eligible but the team did not receive an invitation.

Wyoming followed up that victory with five straight losses: to BYU (44–0), Bowling Green (45–16), New Mexico (24–0), Utah (40-7), and TCU (54–7).

On November 1, the Pokes beat San Diego State, 35–10, at home and then followed with a win over Tennessee, 13–7, on the road a week later.

Wyoming finished the season by losing to arch rival Colorado State, 31–20, at home in the 100th Border War.

During the week before their game against Utah in 2007, Glenn "guaranteed" a victory at a luncheon for University of Wyoming students.

After the play, a furious Glenn was caught giving the middle finger in the direction of the Utah sidelines on national television.

The Mountain West Conference reprimanded Glenn, who would later apologize for the obscene gesture and regretted the "guarantee.

During college, he completed Army ROTC and upon graduation was commissioned as a second lieutenant serving two years of active duty as an MP at Fort Leavenworth, Kansas.
