Kirk Herbstreit has seen Tennessee up close twice already this season. That’s a lot, considering we’ve only reached Week 4.

And the ESPN college football analyst really, really likes what he sees from the 6th-ranked Volunteers, who went to Norman and took down No. 15 Oklahoma, 25-15, on Saturday night. After the Vols’ victory, Herbstreit took to social media to give Tennessee a little love with what he just witnessed.

In his postgame speech to his players, Volunteers head coach Josh Heupel got emotional talking about his return to Norman, where he once starred as the Sooners quarterback. Herbstreit liked that emotion — a lot.

“Some good things brewin in Knoxville. Cool to see Coach getting vulnerable with his guys. Special,” wrote Herbstreit.

Herbstreit didn’t stop there though. He had a specific message for the Vols after the big road win in their SEC opener.

“If @Vol_Football keep their “edge” and can stay healthy they are very real!” Herbstreit wrote. “I’ve called 2 of their games this year-really like this teams potential. Hope they keep playing angry with something to prove. Don’t listen to the compliments-keep your edge!”

Tennessee, which improved to 4-0 on Saturday night, has a bye week now before it visits Arkansas on Oct. 5.
