Ohio State versus Michigan is set for an October football matchup for the first time since World War II but the shots came this week on the Big Ten coaches' conference call, according to a report. Michigan head coach Jim Harbaugh accused Ohio State head coach Ryan Day of allowing on-field instruction before it was to be permitted, to which Day had a swift response. "How about I worry about my team and you worry about yours?" Day told Harbaugh, according to Bucknuts.com.
