Some interesting things I saw regarding us and the Big Ten/ACC Challenge in general on Wikipedia:
We have never played Duke, North Carolina, NC State, or BC.
We will have played FSU and Virginia 4 times each come November, yet we have not played another opponent even twice.
We are 5-8 in the Challenge so far.
We lost 5 straight from 2003-2007 after winning our first 2 and going 3-1 in our first 4, putting us at 2-7 in our last 9.
Iowa holds the record for longest running win or loss streak, having lost the last 6. They were ranked #15 for their last win, being over #21 NC State.
Northwestern and Ohio State are tied for having the longest currently running win streak at 4 each.
The ACC won the first 10 Challenges, the Big Ten has won the last 3.
