Now that's just revisionism. PRX looked really good when Jinggg came back at first - there's a reason going into Shanghai people thought they were the favourites for the tournament. The Shanghai PRX we got however looked nothing like the regional split PRX, the pressure probably got to them and it didn't help that they had no momentum since they skipped the swiss stage as the first seeds, had to face G2 (a team with a playstyle that is bad for them), and honestly should have won vs 100T (that Icebox map was absolutely lost by PRX and gifted to 100T with how many rounds they lost from man advantage).
Then there was the raze nerfs that really hurt them and in champs they had to face G2 again (bad playstyle matchup) and were eliminated by the eventual champions EDG. Obviously to win a tournament you have to be able to beat everyone, but the results honestly make them look a lot worse than where they were actually at (not that they were perfect or necessarily in contention for the trophy - but definitely power wise could have been a lot higher up than where they actually placed - e.g. if it weren't for the gigantic tossing should have been top 4 shanghai, and if different draw, would have made playoffs in champs).
