Not kicking the FG was all part of Mullen's master plan. He knew they would just run it down our throat for a game winning TD on the last drive. He made them play for just a FG because he knew that we would block it.
Only thing I can conceive is Dan didn't know what down it was. Or distance. Or score. Or what yard line we were on. Or that our starting QB had just been hurt. Or that our kicker had just drilled on from that distance.
