A rematch of the 2018 Big Ten Championship Game is set to get underway in just two days, and for at least one side, the implications will majorly factor into the national picture.

With an opportunity for just its sixth game of the season on Saturday, Ohio State is looking not only to win, but prove they deserve a spot among the nation's top four teams beyond a shadow of a doubt.
