Not that it is a huge problem for Ohio State, overall, but Conference image nation wide sure can't be helped here.  

Eastern Illinois @ Minnesota

Jacksonville State @ Michigan State

Indiana State @ Indiana

James Madison @ Maryland

Appalachian State @ Michigan

Northern Iowa @ Iowa

Youngstown State @ Illinois

Sure Wisconsin vs LSU is a marquee game, that will draw a lot of attention to the Conference, but a slip or 2 against any of the 1-AA teams  coupled by toss up games of Northwestern vs Cal and Rutgers vs Washington State, pitting the Big 10 vs the PAC 12, the Big 10 may well be behind the 8 ball before the season is even 72 hours old, in terms of Conference Champ jockeying for a playoff spot.
