Now in its thirteenth year, the annual Big Ten/ACC Challenge is always an entertaining tour of the college basketball world, but this year is extra special, as all twelve teams in both conferences will participate, thanks to the addition of Nebraska to the Big Ten. While the Challenge has historically been controlled by the ACC, winning the first ten times these two conferences tangled, the Big Ten has won two in a row, and is in good position to make it three this year. Lots of talent, lots of tangles...it's what college basketball should be. And what college football should try, too.
