Brian holds the high card here. He can pick Bama which is the safe and logical choice. mancha won't know whether Brian picked Bama or not before the game starts but he will have to assume that Brian would pick Bama. This forces mancha to pick Clemson because the only way he can win is to pick the opposite of Brian's pick.
Slight diversion from college football. I just saw the news on ESPN that Mean Gene Okerlund had passed away at the age of 76. He was an announcer/analyst/interviewer in pro wrestling. His interviews used to crack me up. Such seriousness in a funny situation. He was one of a kind.
