According to Football Outsiders and any other sports media source:
INFIGHTING ILLINI.
Illinois had many, many problems against Ohio State, but the offense wasn't one: Despite the haplessness of the defense, the Illini managed to generate 420 yards and 35 points, as many as they've scored at any point in their ongoing, 20-game Big Ten losing streak. As usual, though, when things went wrong they went really wrong. In the third quarter, with the score still conceivably within reach at 35–21, starting quarterback Nathan Scheelhaase left the game for one snap after his helmet came off during a play; in went backup Reilly O'Toole, who was immediately sacked, fumbling the ball into the end zone for a Buckeye safety.
It was at this point that head coach Tim Beckman had to be forcibly restrained from assaulting his offensive coordinator.
