In one video of the scene, shot by Notre Dame beat reporter Tyler Horka, you can see Brey took down a shot of Jameson's with a couple Irish supporters -- all while Morgan Wallen blared over the bar's speakers.
Later, Brey was spotted chatting it up with nearly everyone in the room ... making sure a drink was firmly in his hand.

Of course, Brey had every right to turn back the clock and celebrate like a college student -- because the win earlier in the evening capped off a hell of a run at Notre Dame's home gym for the coach. He improved his record with the win to 315-76 in front of home crowds.
After the game, Brey took a bit of a victory lap around the arena -- before he triumphantly walked off the court.
