Ohio State has not been an underdog to a Big Ten team in five years. Michigan is poised to end that streak Saturday.
The Wolverines began the week as 4-point home favorites over the Buckeyes at ESPN BET. It's the first time they've been favored over Ohio State since 2018, when the Buckeyes were also 4-point underdogs against Michigan.
That was the last time Ohio State had been an underdog to a Big Ten team, a stretch of 43 games against conference foes. It's the longest active streak of being favored against one conference in the nation, according to ESPN Stats and Information.
