BATON ROUGE ­— The 24-hour celebration rule is probably outdated anyway.

But LSU didn’t have long to bask in its shocking upset of Florida Saturday.

Less than a day later came word that head coach Ed Orgeron will be let go from his dream job at the end of this season — less than two years after winning the national championship with a 15-0 record.

Rare for such occasions, Orgeron and the man who fired him, athletic director Scott Woodward, appeared together at a hastily called press conference Sunday night.

Woodward praised Orgeron and called him a personal friend.

“But the job of ours is to set personal feelings aside and make decisions that are ultimately best for LSU,” Woodward said, adding that the goal is always to compete for SEC and national championships.

“Our last two seasons have simply not met that standard. We determined it was time for us to move in a different direction.”

Orgeron wasn’t surprised.

“I just felt like after the Kentucky game (a 42-21 loss), I knew it wasn’t pretty. I was embarrassed.

“After he came and talked to me after the Kentucky game, I knew that it was time.”

SI.com’s Ross Dellenger first reported the news, also quoting sources as saying that Orgeron will receive the entire buy-out in his contract, which is just below $17 million. A USA Today report last week listed Orgeron’s $9.01 million annual salary as No. 2 on the list of college football’s highest-paid coaching, behind only Nick Saban of Alabama.

Although it was old news by then, LSU’s players were informed of the decision at a team meeting Sunday night.

“I’ve been telling the kids. I’m going to finish with this team,” Orgeron said. “I love this team, I love LSU.”

He also said he would continue his recruiting efforts.

“I’m going to tell them to come to LSU,” he said. “I recruited them to come to LSU. Why would I tell them anything different now? I met with two today.”

Woodward, known for making flashy hires at his previous stops at Washington and Texas A&M, said the search for Orgeron’s replacement “begins today” but would not elaborate on any potential candidates.

“This day is about Coach O and what he’s meant to this program,” he said.

At least one former Tiger — the most famous of them all — was not happy with the news.

“That’s disappointing to me,” Cincinnati Bengals quarterback and LSU Heisman Trophy winner Joe Burrow said after leading his current team to a 34-11 victory over Detroit. “He’s really a man that gave me an opportunity when really no one else was. I wouldn’t be here without Coach O and I’m forever indebted to him as a person and a player.

“Our relationship will continue for the rest of our lives, I love the man, I love the coach.

“They haven’t been winning as many games as I know they’d like but we did just win a national championship two years ago. So that’s disappointing. I love coach O and everyone over there. I hope he’s able to find a place where he feels he’s welcome.”

Orgeron said he didn’t plan to coach anywhere next year.

“I want to take a little time off,” he said. “I’m 60 years old. I’m going to have enough money to buy myself a hamburger. Maybe a double-meat cheeseburger.”

Orgeron, a Cajun to the core who made no bones about LSU being his dream job, didn’t care at all that he wasn’t the school’s first choice when he earned the job full-time after going 5-2 as interim head coach after Les Miles was fired.

LSU’s faith paid off with that 2019 undefeated national championship team that was considered one of the best in college football history.

But Orgeron is only 9-8 since that magical 2019 season. The Tigers, hit by numerous opt-outs, had to win their final two games to finish 5-5 in last year’s pandemic-shortened season and got off to rugged start this year with opening loss at UCLA.

LSU, riddled with injuries most of this season, lost back-to-back games against Auburn and Kentucky in ugly fashion before rebounding Saturday for the 49-42 upset of Florida.

“I don’t have the answer to what went wrong,” Orgeron admitted. “If I had the answer, I’d have fixed it.”

“When you win you’re doing everything perfect. When you lose you’re not.”

“It was a great run … the last two years were not the LSU standard.

“But I’m honored that I got to be the head coach at LSU.”
