Well, first of all, I totally agree. According the ratings and PP100, I had no business winning that game. But, in my defense, I think 'couldn't win a game' is slightly wrong. I didn't win many games, but then again, I didn't need to. Very early on it was clear that trying to get to the #6 seed wasn't worth the enthusiasm, so I was able to work on other things.
But back to your main point, that game was pretty backwards, and I don't expect the next two to look like that.
