The Ohio State mascot Brutus trolled Lou Holtz after Ryan Day's Buckeyes won the college football national championship vs. Notre Dame.

Fans couldn't help but make all kinds of jokes about Lou Holtz and Ryan Day after Ohio State football's win over Notre Dame.

Ohio State has embraced their new rivalry with Lou Holtz, and some Buckeyes fans trolled the legendary Notre Dame coach with an awesome sign during the College Football Playoff National Championship game on Monday night.

Former Notre Dame head coach, Lou Holtz, is at it again. The former Fighting Irish head coach loves to keep his name in the headlines any way he can, and now he’s using a beef with Ohio State’s Ryan Day to do just that.

Lou Holtz may not get to celebrate a Notre Dame title in Atlanta. Notre Dame is down 31-23 to Ohio State in the National Championship Game. The Fighting Irish allowed 31 straight points after opening the contest with a 15-play touchdown drive that lasted nine minutes and 45 minutes.

Former Notre Dame coach Lou Holtz and Ohio State coach Ryan Day are still trading barbs before both teams play each other in the College Football Playoff national title game.

"Where is Lou Holtz?"  That question is going to be asked all week leading up to the College Football Playoff championship game between No. 7 Notre Dame and No. 8 Ohio State at Mercedes-Benz Stadium on Monday.

The legendary coach reignites a rivalry with his unfiltered take on the Buckeyes before their national title clash with Notre Dame.

It should be noted Holtz was an assistant at Ohio State during the 1968 championship season under Woody Hayes, so he has a little Scarlet and Gray in him as well.

Brutus Buckeye and Ryan Day fire back at Holtz's controversial comments after the Buckeyes secure the national title.

Holtz, 88, reignited their feud last week on X when he wrote that, “If Notre Dame doesn’t win, it’s because we want to preserve Ryan Day’s job. I was originally going to be at the game in spirit, but now I’ll be dragging my body along as well.” He was responding to a tweet wondering if he would attend the showdown.
