I have no idea what to expect for the 98th Little Brown Jug other than cold weather.
On one hand, PJ's Gopher teams have been notoriously slow starters. They've had trouble putting away bad non-cons and 1-AA tomato cans, and Michigan is a lot better than any of those. Also, a lot of losses on D starting with a safety who is now a starting safety in the NFL as a rookie. On the other hand, all the offensive weapons that had the league's best bowl win are back with a chip on their shoulders. Should be a great ball game.
Also, yours truly was at the Big House for that celebration with the Jug back in 2014. After not seeing a Gopher road win in person in 11 years of trying, I saw two that fall. It was glorious.
