BYU head coach Bronco Mendenhall mentioned on his weekly radio show this week that he "would love to have a long term agreement with Boston College. I think that would be a great game for us. And then there's many others that will be announced later that I think the fans will really like." If I am reading into this quote correctly, it appears that a deal with BYU is in the works. The earliest this game could happen would be 2016 due to BYU having a full schedule next year and BC being complete in 2015.
Provo is a beautiful place to see a football game and the fans are polite and inviting. Just don't plan on an alcohol fueled tailgate. I didn't see a drop of alcohol when I was there in 2010. But nonetheless, I think this would be an exciting rivalry and BYU's status as an independent could provide BC with some exposure.
