Jerry Glanville now spends his time as the defensive coordinator of the Tampa Bay Vipers of the XFL after once being a memorable character in the NFL.

After his NFL career came to a close, and he bounced around at different jobs in different leagues, Glanville thought he was finished with coaching. Then, a visit to Iraq speaking with military servicemen was able to convince Glanville to make a valiant return to coaching.

“They said, ‘You’ve got to come back to coach because our grandparents tell us about you and we’ve never seen it,’” Glanville recalled via the Tampa Bay Times ahead of another XFL weekend. “When I came back from Iraq, I started coaching again.”

In the early 1990s, Glanville was best known as the head coach of the Atlanta Falcons. The charismatic coach would go 27-37 in his four seasons with the Falcons. Unfortunately, after spending 20 seasons in the NFL, Glanville's coaching career was seemingly over.

Following a 12-year hiatus from football, Glanville returned to the sideline as the University of Hawaii's defensive coordinator. Just two years ago, Glanville was the defensive coordinator of the Hamilton Tiger-Cats of the Canadian Football League.

Now, at 78-years-old, Glanville finds himself staying busy, dialing blitzes on defense in the XFL.

In Tampa Bay's game last Sunday, Glanville's defense held the DC Defenders to zero points. As a matter of fact, it was just the second shutout in the XFL's short history.

While he was overseas, Glanville didn't envision himself wearing a headset this year. However, it didn't take much convincing for him to return to the sideline as a defensive guru.
