Quarterback question: Who will the Wolverines play at quarterback: injured starter Wilton Speight or backup John O?Korn? And if Speight is healthy enough to play, how effective will he be returning from the collarbone injury? O?Korn struggled enough last week in the passing game that there?s doubt about his ability to be a threat there. Maybe Speight was taking reps just for show, to create doubt for the Buckeyes. Or maybe he?ll return at the biggest moment and save the Wolverines. U-M?s bad QB injury luck before and during this game in the last decade is wild: Chad Henne in 2007, Denard Robinson in 2012, Devin Gardner in 2013, Jake Rudock in 2015 and now Speight.
