WATCH: LSU football player mocks DC Matt House and his dismissed defensive crew by kicking rocks on IG

LSU Tigers coach Brian Kelly let go of his defensive coordinator, Matt House, on Wednesday. This made at least one player happy with the move, who mocked House and three assistant defensive coaches on Instagram after they lost their jobs.

Edge Brady Swinson shared a video on X of a person kicking rocks after the news of the firing broke. And he accompanied that with a cryptic message pointed in House’s direction:

“IYKYK (if you know, you know).”

The Tigers had a great year offensively, with quarterback Jayden Daniels winning the Heisman Trophy. But their defensive performance left a lot to be desired. And it looks like House and his staff did not have the locker room backing toward the end of their tenure.

The Tigers (10-3) were considered contenders for the national championship this season, ranking fifth in the preseason poll. But their defense held them back, allowing at least 42 points in their three losses, including a 55-49 loss to Ole Miss in which the Rebels scored 15 points in the final five minutes.

The LSU defense ended the season with a rank of 105 in the country, allowing 416.6 yards and 28.0 points per game.

While Matt House's defense struggled, Mike Denbrock’s offense flew

The LSU defense under Matt House did not fulfill expectations. But the Tigers offense did its job brilliantly during the 2023 season. Heisman-winning quarterback Jayden Daniels was at the center of everything, putting up a string of performances to take the team forward.

Daniels had career highs in passing yards (3,812) and touchdowns (40) and also showed his scrambling and rushing ability with a career-high 1,134 yards. The dual-threat QB has ten rushing touchdowns, bringing the tally of his total scoring plays to 50.

The 13th-ranked Tigers, who averaged 45.5 points per game and scored 79 touchdowns, ended the season by defeating the Wisconsin Badgers 35-31 in the ReliQuest Bowl.
