CHICAGO (AP) – Michigan coach Jim Harbaugh once again declined to identify his starting quarterback for the opener on Saturday against Hawaii. It is expected to be either Wilton Speight or John O’Korn. Harbaugh says the quarterbacks and rest of the team all know but he’s not letting the choice out for public consumption. During a Big Ten coaches’ conference call with the media, Harbaugh, whose 1986 Wolverines team won 27-10 at Hawaii to finish the regular season when he was the quarterback, said he’d “definitely consider” a return visit to the island state for his program in the future. Michigan also traveled across the Pacific Ocean in 1998, when a quarterback named Tom Brady led the Wolverines to a 48-17 victory over the Rainbow Warriors.
