You have a great memory!
After we played at their place about 10 years ago (I was there, but can't remember the year), we had a return game scheduled. I believe that would have been around 2011 or 2012. Anyway, they ended up cancelling and buying us out. I don't recall any more of the details.
I'll take these games however we need to get them. Same with the Illinois game. But, I give serious props to Indiana and Syracuse who gave us return games in exchange, just like Kentucky is committing to right now.
