The last time that the Americans had won Ryder cup was in 2008 and Europeans have won seven out of the nine times the event has been held. The guys like Rory McIlroy, Lee Westwood and Sergio Garcia consider most of the important event as road games.
What would be the scene if Americans too took part regularly. If they participated in most of the events such as go Argentina to compete against Angel Cabrera or to Spain to fight against Miguel Angel Jimenez or Japan to go against Hideki Matsuyama. Obviously it would not be nice.
