Miracle in their own right to make it this far in the tournament with a sub. Unfortunately, it’s going to catch up with them eventually. NRG look shaky as hell, so I don’t see it out of the realm of possibility to beat them. That being said, EG and Fnatic are practically unbeatable atm.
They can definitely beat NRG, although they aren't favored against them. EG would have to choke due to inexperience or pressure or something, and beating FNC just seems too hard tbh. Would take a miracle, but I would say its not impossible.
