Entering his third season in charge of college football’s winningest program, he’s refusing to unveil his roster until three days before No. 11 Michigan kicks off the season against No. 17 Florida in Texas.

And he won’t say whether returning starter Wilton Speight or seldom-used senior John O’Korn will take the first snap Saturday against the Gators at the home of the Dallas Cowboys.

“Have not heard Florida announce who their starting quarterback would be,” Harbaugh said Monday. “We’d love to have that information. No, we’re not announcing our starting quarterback. People make a lot of a big deal about our roster or not announcing a starting quarterback.”

NJ Advance Media, attempting to identify New Jersey natives playing in the Big Ten, submitted a Freedom Of Information Act request to obtain the Wolverines’ roster. The list was not published online or printed on paper when the team had spring practice or reported for training camp this summer.

Michigan football coach Jim Harbaugh, shown here on July 17 in Ann Arbor is playing games of another kind — keeping his roster secret. He also won’t say whether returning starter Wilton Speight or seldom-used senior John O’Korn will take the first snap for the 11th-ranked Wolverines against No. 17 Florida in Texas in the opener for both schools.

Harbaugh is holding to his plan to “determine and publicize” the final roster on Wednesday.
