A year after hearing chants of "O-H, I-O" inside their own stadium, the Sooners got revenge on Saturday night as the Heisman Trophy hopeful threw for 386 yards and three second-half touchdowns.
Mayfield sprinted around the field waving a Sooners flag before stopping to emphatically plant it in the middle of the huge block "O" logo at the 50-yard line as his teammates cheered.
"I didn't mean for it to be disrespectful to any Ohio State people at all, especially the team or the players, because they're a great team and a great program," Mayfield told reporters Monday. "It was an emotional game. I knew that it was going to have a lot of implications on the playoffs. ... I got caught up in an emotional win. Yeah, it should've been something I did in the locker room. So I apologize for doing it in the middle of the field."
Mayfield, who completed 27 of 35 passes, said he understood why Buckeyes fans and players were upset about the celebration.
"If they did that here (in Norman) I would've been pissed, too," Mayfield said. "I understand why they're very upset about it. But I didn't mean it to be disrespectful in any way."
After the game in Columbus, Ohio, an emotional Mayfield talked about flipping the script between the then-No. 5 Sooners and then-No. 2 Buckeyes.
"That was embarrassing to have them singing their fight song on our field (last year)," Mayfield told reporters Saturday night. "They're probably feeling that way right now. ... We should have won by more.
"We've had that mood in the locker room that nobody believes in us. Nobody picked us on (ESPN) GameDay. We believe in ourselves, and that's all that matters."
