If C9B actually lose this bo3 to Rise then they're not top 8 NA anymore, and it just proves that ShahZam was right about them, and that their run during the playoffs was just a fluke. They could redeem themselves in Challengers 2, but I'd doubt it. All the top tier NA teams did lose maps to tier 2 teams like Rise, sure, but they still came through and closed out the series. Being 'rusty' or the other team being 'lucky' is not an excuse to lose an entire Bo3, only valid for losing a map.
Triggered C9B fans can cry all they want, but their team will not be top 8 for a good 2 weeks after this, if they lose LOL.
