CHAMPAIGN, Ill. -- So when does Ohio State-Michigan week begin? How about virtually as soon as the final seconds ticked off the clock Saturday at Memorial Field? Exactly. You almost felt a sense of pity for the Illinois fans, who were still fired up moments after the Buckeyes beat the Illini, 30-20, on Saturday. By the time the Ohio State players had finished singing “Carmen Ohio” and made the diagonal run across the field toward the locker room, Illinois was history. Sorry, Illini fans. The Illibuck Trophy is nice and the Buckeyes did want to avenge that loss to Illinois in Columbus last season, but there simply isn’t any time to dwell on the game that precedes Ohio State’s annual date with Michigan. Buckeyes coach Jim Tressel, who can tell you in March how many days remain until his team meets the Wolverines once again, devoted just enough time to Ohio State’s victory over Illinois in his postgame news conference. But then it was time to turn the page.
