Until its 4-1 loss Thursday night against Argentina in the Copa America, the U.S. men's national team was undefeated -- 10-0-1 - since Bob Bradley took over as head coach in December. The USA's last loss was more than a year ago, the 2-1 defeat to Ghana at the 2006 World Cup. The U.S. women are undefeated for more than a year. Coach Greg Ryan's team is on a 43-game unbeaten streak -- 24 of those games came in the last 12 months, which means that before the men's Copa loss, U.S. men's and women's national teams were 31-0-4 over 365 days.
