Headsets are staple in college football. It’s become so common that we don’t even recognize it much anymore. Unless, of course, you’re Jim Harbaugh slamming it into the ground or Urban Meyer throwing it into the stands.

Those are really the only instances when a headset is even mentioned. But ESPN recently dove a little deeper into the history of the headset in college football. And the network sure got some interesting content.

ESPN reporters Adam Rittenberg and Chris Low spoke with several college football coaches, asking them several questions regarding the conversations occurring under the headset. As you could’ve probably guessed,  there’s a lot of back-and-forth, plenty of swearing and even some “firings.”

First, the story touches on headset etiquette. And this was quite the gem from former Alabama offensive coordinator and current Florida Atlantic head coach Lane Kiffin:

The second headset commandment: No hurt feelings. Just listen to the most famous example from recent years, ex-Bama offensive coordinator and current FAU coach Lane Kiffin: “I learned from my last boss [Saban] to tell my staff prior to games, ‘Hey, don’t take anything personal or be too sensitive because things are going to get said really fast.’ I had plenty of experience with that in my three years at Alabama — taking all those ass-chewings reminded me to warn my coaches in advance.”

We all remember those, right? And Saban didn’t even need a headset for chewing out Kiffin.

Then, the story dove into some of those “firing” stories. One of which involved former Penn State offensive coordinator and current Mississippi State head coach Joe Moorhead:

As a grad assistant with Pitt in 1999, Joe Moorhead was canned over the radio multiple times by D-coordinator Larry Coyer after flubbing a personnel package. But not really. Moorhead rose from that position to eventually become Mississippi State’s head coach. And now? Coyer works for Moorhead as an analyst in Starkville.

Those are just a few of the highlights from ESPN’s story. There are plenty of great stories from several recognizable head coaches.

Other coaches mentioned were West Virginia’s Dana Holgerson, Auburn’s Gus Malzahn and retired Florida and South Carolina head coach Steve Spurrier.
