I'm gonna try jump in before this balloons. This was a 30 second clip from a 6 and a half hour stream VOD reviewing the 4 games. There's a huge amount of context that isn't here and I'm summarising for the sake of brevity.
When I say "played better" I mean as a team they made better decisions more often than G2 did. In many ways, their drafts made it harder for them to win but not impossible. But if we take game 2 as an example, the first 6 kills that SKT got were actually just G2 making terrible decisions or they were getting punished by SKT. In game 4, Caps just ran into 4 members of SKT to try and kill mata, which baited his whole team into a horrendous teamfight. They made greedy plays, they forced plays that didn't make sense WHILE ALSO doing incredible things. That's why I say overall. Some of the decisions these players made to compensate for some of the mistakes of their teammates was incredible. This team constantly thinks outside the box and constantly finds new ways to solve every problem.
Ontop of that, G2 executed so many fights better than SKT, but because of how they drafted it was also harder to execute those comps. If we arbitrarily say a comp takes a skill of 2 to teamfight with vs a comp that takes a skill of 4, then you can understand better the situations SKT would often have to create to win these fights.
None of this should take anything AWAY from G2. This team plays very differently depending on their opponents and they're also very self-reflective. They recognize what they need to improve on and they often do it. They were the better team and they deserved to win that semifinal, but that doesn't mean they were perfect in doing so.
