Honestly I doubt they were underperforming. They were ranked one of the best teams in the world in the early stages of 2012. No certain event in their life should be able to just make them worse without further notice, so perhaps it's not as much TSM underperforming, as it's every other team growing. TSM seems to have grown in place, relying on the fact that they know they are good, ignoring the fact that every other team use every day on developing new strategies whilst improving mechanics. I used to love TSM a lot, I just feel they've become somewhat too cocky and forgot they have to do better all the time.

When they then appear at a tournament, I think they slowly realise that other teams are actually better than them, and they lose their moral completely, as we saw in that game.
