IMT is the only one I would say is guaranteed. Even if they play badly their competition beyond LZ is way weaker.
C9 has good chances in paper but their adversaries are much tougher. AHQ loves to pull upsets, and EDG is paying at home so even if they are eliminated early I can see them trying hard to score a win.
TSM needs to beat WE. Losing to WE they miss a potential head-to-head win. Basically a repeat from last year.
FNC is done, nothing to say here. They needed to win that game against IMT.
G2 have more chances than it would appear. They are good enough to beat a disappointing SSG and Zven is one of the few botlanes I can see beating UZI. They just need Trick to play well for 2 games straight an then collect a free win against FNB.
MSF is a good job, basically all I said about TSM applies to them, just trade WE for TSM themselves.
