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

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

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.

"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.

Lou Holtz might not be the president of Ryan Day's fan club, but he knew how Ohio State would perform on Friday night against Texas. Several hours before the Cotton Bowl kicked off on ESPN, Holtz revealed his prediction on social media.

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.

Ohio State and Notre Dame will square off in the College Football Playoff national championship on Jan 20 in Atlanta.
