Urban Meyer leaves Jaguars after 13 games. It's not the only similarity to Bobby Petrino.

Urban Meyer's early departure from Jacksonville brings to mind another college football coach who failed to make it through his first season in the NFL.

The Jaguars fired Meyer in the wee hours Thursday morning after a 2-11 start to the season. The poor record came with a long list of controversies, from the hiring of Chris Doyle to the dancing video at his Ohio sports bar, from reportedly calling his assistants losers to reportedly kicking Josh Lambo before a preseason game.

Meyer lasted the same amount of games as Bobby Petrino, who left Louisville to coach the Atlanta Falcons in 2007. Petrino went 3-10 with the Falcons before leaving for the head coaching job at Arkansas. He infamously left behind just a note to his staff and players in the locker room bidding them farewell.

(To be fair to Petrino, he came to Atlanta expecting to have Michael Vick as his quarterback. Vick was arrested on federal dog-fighting charges that offseason.)

Meyer left on similar terms, according to The Associated Press' Mark Long, who tweeted Meyer "left the Jaguars facility after practice (Wednesday) and never returned, leaving staff to prep (for Sunday's game vs. the Houston Texans) without him."

What are the shortest NFL coaching tenures?

Meyer and Petrino didn't make it through one full season, but they're not the shortest coaching terms in NFL history.

Lou Holtz, another college football great, coached the New York Jets for 13 games as well in 1976. Like Petrino, he went 3-10 and resigned before the last game of the season. Also like Petrino, he went to Arkansas after his failed NFL stint. 

Pete McCulley, a longtime NFL assistant, finally got his chance as a head coach in 1978 with the San Francisco 49ers. He lasted just nine games, going 1-8 before being fired.

But that wasn't even the shortest coaching tenure of the 1978 season. George Allen coached just two preseason games for the Los Angeles Rams before he was fired. It was the Hall of Fame coach's third stint with the Rams. There was a reason they brought him back: Allen never had a losing season in his 12 years as a head coach.

And perhaps the strangest tenure of all: Bill Belichick and his one day with the Jets in 2000. At his introductory news conference, where he was to take over for his mentor Bill Parcells, he announced his resignation. He went to the New England Patriots, instead. You know the rest.
