TH might be the team that can go on a run. Their performance has been underwhelming, but I believe all the extra time they got might help them, and if Miniboo performs decently, TH will clear G2.
Also, if DRG beats T1, then G2 can qualify; otherwise, T1 will beat G2. Every player on T1 is good, and if they can put in the team effort, they will eliminate G2.
