The Buckeyes have been favored in its past 51 games, the longest such streak in the nation that dates back to the 2015 College Football Playoff championship.
That streak is over.
Caesars Palace, in Las Vegas, on Sunday installed the Buckeyes as 3.5-point underdogs against Michigan.
The Wolverines are favored over Ohio State for the first time since 2011, when Michigan knocked off the Buckeyes 40-34 as 8-point favorites. It was the Wolverines' last win in the series.
