So I couldn't disagree more with your assessment that the difference was the Euros not being the Euros. they're not invincible. With the exception of Sergio, the Euros were every bit as good as they've always been. I don't see which household names played poorly. Heck, even Westwood played well. He just ran into Boo who played out of his mind. So I think the best Euros showed up, except Sergio and Harrington (and Harrongton hasn't played well in the Ryder Cup in a while now, so I don't think that was much of a surprise). I believe this US Ryder Cup team would have won any of the previous 3 playing the way they played.
The Euro's top three of Paddy, Sergio, and Westwood (I believe) didn't do much to help the Euros. I don't think they won a match. I think Azinger made his best decision sending Kim out as the first US golfer on Sunday. From what I saw of the cup Kim looked excited and pumped up to be there. He took Sergio behind the woodshed beating him handily. I think that set the tone for the rest of the day.
On a side note Polter played amazing this weekend. Wow was he clutch. Boo's comment about his bunker shot being his 9th best was classic. How about Kenny Perry's dad coming onto the course after Perry won in overalls. Sergio is a class act, after the Americans won Sergio went over and congratulated the American team.
