Based on the current AP Top 25, Ohio State faces its biggest test of the season to date on Saturday.
Illinois is ranked 17th in the country after a 5-1 start to the season, setting up a clash of top-20 teams as the No. 1 Buckeyes travel to Champaign. The Illini will be looking to make up for their 63-10 blowout loss to Indiana in their biggest game so far this season, while the Buckeyes look to extend their winning streak dating back to last season to double digits.
The game will serve as a barometer of how good both teams are as the Illini look for an upset that would put them back in the College Football Playoff conversation, while the Buckeyes look to handle business on the road for the second time this season.
