It would have been a great season if we’d won this game, but we couldn’t get it done. My feeling about the team is we’re right there at the top. But we have to put it over the top, especially in the big games at the end of the year.”The 2019 season will be a massive one for Michigan. The Wolverines will get to play an Urban Meyer-less Ohio State team with several other Big Ten teams going through major changes. Harbaugh has to deliver on the biggest of stages.
