why Harvard beat Yale so often.

for Yale athletes we need to invent a special pill - when the pressure is on, it turns your nerves to steel..  all games come down to doubling your focus for the 1% of the game that determines 100% of the result.  Harvard guys pounce on those few moments because at heart they are lazy and dont want to work hard for a full game.  They know that the 1% is all that matters and they eagerly wait for it. 

Yale guys believe in an all out effort 100% of the time.   When those few moments occur that demand the extra effort to win, they are so exhausted that the reality of the situation freezes their hearts. 

this is an ancient malady that all comes down to the chemistry of the mind during those few precious seconds.
