Paper Tiger in the home of the Sound Tigers?

An ECAC Team as the top seed in the NCAA Div I hockey tourney? Ivy League no less. the Yale University skating Bulldogs. As number one seed in the East regional they play Air Force, second place finishers from a conference no one has heard of (Atlantic hockey). Should be automatic, right? they played a scoreless 1st period, with Yale carrying most of the play, but Air Force with the greater number of "Grade A" chances (3-2). Air Force beat them head to head in November, and posted a win in this same Bridgeport building 2 years ago against a dominant Michigan team. So...this has become a pick 'em game. #1 vs #20. Go figure. Yale has some serious work to do if they are to get to their historic first Frozen Four.
