ANN ARBOR, Mich. — By the time Jim Harbaugh walked onto the court at halftime of the Michigan basketball game, his homecoming had turned into a full-fledged pep rally. "I pledge to you that we will do our very best to carry on the great tradition of Michigan — excellence all across the board," the Wolverines' new football coach said to the cheering crowd at Crisler Center during Tuesday's matinee win against Illinois — in an overtime thriller, naturally. "You know how to make a guy feel at home," Harbaugh yelled, his voice sounding hoarse from a whirlwind few days.
