Fervent Ireland rugby fans were in shock on Saturday but also praised Rugby World Cup host Japan for a stunning 19-12 win over their team, which entered the tournament ranked No. 1 in the world."I feel that you never underestimate your opponents. Never," said Nigel Keane, a 52-year-old driving instructor from Dublin who watched the game at Shizuoka Stadium Ecopa. "It was a good match. You can't substitute skill for guts and determination.""I think Ireland have to put in two more good performances to go to the quarterfinals."
