One of the final games in this year's ACC/Big Ten Challenge is the most interesting game in this year's ACC/Big Ten Challenge. It's North Carolina at Indiana - otherwise known as a Wednesday night showdown between the two schools that can, at this point, reasonably be picked to win the ACC and Big Ten. Tipoff is at 9:15 ET on ESPN.

If North Carolina wins, the Tar Heels will own a victory equal to, if not better than, Villanova's win at Purdue. Additionally, they'll solidify themselves as an undeniable national championship contender, and improve to 2-0 against Big Ten powers.

UNC beat Wisconsin 71-56 last week.

North Carolina is No. 3 in the updated CBS Sports Top 25 (and one).

Indiana is No. 15.
