While this probably doesn’t fall under the “You Only Had One Job” moniker, it’s pretty darn close.

Tennessee Titans head coach Brian Callahan admitted he made a massive mistake in a 20-12 Week 1 loss to the Denver Broncos in which he incorrectly decided not to challenge a call that ruled a 23-yard catch made by rookie wide receiver Elic Ayomanor.

Ayomanor managed to make the catch and get his elbow down before going out of bounds.

“An elbow doesn’t equal two feet, so his foot would’ve had to come down as well,” Callahan said after the game on September 7.

That’s not accurate. NFL rules state either 2 feet need to come down inbounds or any body part other than the hand.

“My interpretation of the rule was wrong,” Callahan told ESPN’s Turron Davenport on September 8. “I’ll own it.

I didn’t do a good enough job in that moment, and I should have challenged it, and it probably would’ve resulted in a potential explosive play.

“I misspoke. I’m well aware of the rule, I understand how it works, and the way that I articulated it afterwards was incorrect. And I understand the rules of this game pretty well.”

In all reality, Callahan does not. His coaching to this point in his career kind of reflects that.

Callahan, 41 years old, is in his second season as Tennessee’s head coach and it very well could be his last — he went 3-14 in his first season in 2024 and a repeat performance could earn him his walking papers.

Callahan’s Gilded Path To Becoming NFL Head Coach

Nepo Babies aren’t just for Hollywood.

The NFL has plenty of them as well, with Callahan just being the latest example. He’s the son of former NFL head coach and University of Nebraska head coach Bill Callahan, who is currently the Titans offensive line coach.

Interestingly enough, Bill Callahan’s NFL head coaching career only lasted 2 seasons with the Oakland Raiders, where he led the franchise to the Super Bowl in 2002 before he was fired after going 4-12 in 2003.

Bill Callahan got another shot as a head coach at Nebraska from 2004 to 2007, where he was fired after going 27-22 in 4 seasons, including a 15-17 record in Big 12 play.

Brian Callahan made his way up the coaching ranks as an assistant for the Broncos, Detroit Lions and Raiders before spending 5 seasons as the offensive coordinator for the Cincinnati Bengals from 2019 to 2023 before he was hired by the Titans.

Nepo Baby Head Coaches In NFL: Nothing New

Callahan isn’t the first NFL head coach to have gotten a job based solely on his name.

Legendary Miami Dolphins head coach and 2-time Super Bowl champion Don Shula’s son, Dave Shula, went 19-52 as the head coach of the Bengals from 1992 to 1996.

Current San Francisco 49ers head coach Kyle Shanahan is the son of 2-time Super Bowl champion head coach Mike Shanahan and was 70-62 headed into his ninth season in 2025.

Rex Ryan, the son of legendary NFL defensive coordinator and former Philadelphia Eagles head coach Buddy Ryan, is perhaps the famous Nepo Baby NFL head coach of all time — he went 61-66 over 8 seasons as the head coach of the New York Jets and Buffalo Bills.
