No cold, virus or flu can keep Baker Mayfield from trolling his haters.

The Oklahoma quarterback, never one to let a jab at the Sooners pass him by, arrived at the Rose Bowl ahead of today’s national semifinal against Georgia carrying a sign with the word “pretenders” written on it. It’s a dig at ESPN’s Lee Corso, who back in August called the Sooners “pretenders” on ESPN’s College Gameday. (Corso, meanwhile, actually picked Oklahoma to win on Monday.)

If any more proof was necessary that Mayfield isn’t messing around, he took the field for the Sooners’ first drive of the game and led an 80-yard march over six plays, completing all four of his pass attempts for 63 yards, including a 13-yard touchdown to Marquise Brown.

The flu-like symptoms Mayfield dealt with this week apparently haven’t dulled the Heisman Trophy winner one bit. After much fussing over his health heading into the Rose Bowl, Mayfield reportedly went through his normal pregame routine before playing his first game after a 30-day layoff for the Sooners.

Mayfield entered the semifinal with the second-most passing yards (4,340) and passing touchdowns (41) in the country to augment his clap-back skills on Twitter.
