Griffin, who won the Heisman Trophy in 2011 and had one win over Oklahoma during his collegiate career, dubbed Riley a “genius” for getting out as the Sooners are only a few years away from joining the SEC.
“Lincoln Riley is a genius. Don’t go to the SEC and be little brother to Alabama and Georgia. Go to the PAC 12, revive the USC Juggernaut and further cement your coaching legacy,” he wrote.
Griffin also responded to one tweet, saying Riley was playing “chess not checkers.”
Riley decided to take the vacant USC job after the school parted ways with Clay Helton earlier in the season.
“My time at OU has included some of the most special years of my life and my family’s lives. I had so many great memories and made so many great friends that we’ll take with us forever,” Riley said. “A lot of things that we were a part of here, I’m incredibly proud of — the success on the field, the success off the field, the players. Proud of the staff. Proud of the way we worked so well with the university and our administration. We’ve been able to have two phenomenal leaders in President Joseph Harroz Jr. and Joe Castiglione, and they have been everything I could ever ask for in this role and more.
Riley said his decision was “personal” in hopes of taking on a new challenge elsewhere.
“Leaving OU was probably the most difficult decision of my life. OU is one of the best college football programs in the country, and it has been forever. That’s not going to change. It’s not going to change in the SEC, it’s not going to change with another head coach. It’s stood the test of time, and it’s going to continue to do so. This was a personal decision solely based on my willingness to go take on a new challenge, and I felt like it was the right opportunity for me and my family to do that,” he said.
“We’ll leave here with fond memories. It’ll be very difficult to say goodbye to Norman, but it will always be a part of our family, our history. I’ll be a Sooner fan as long as I live — a fan of this state, of this university and the people here. I love them all very much.”
