It's the 101st meeting between Illinois and Ohio State, and both teams are looking to prove doubters wrong.
Nothing about college football in 2015 is easy to predict. At the beginning of the year, Auburn was supposed to win the SEC (but not the SEC West, because reasons), Oregon was expected to reload, Clemson was supposed to Clemson their way to two or three losses and Iowa was supposed to finally have a season that would allow the powers that be to spend money to give Kirk Ferentz the boot. At home in Columbus, Ohio State was supposed to run through its schedule with little or no effort, and put itself in line to repeat as College Football Playoff national champions.
