Will lose today.
I could see Sentinels underperforming a little during their first game of the tournament. And while G2 isn't the best they still have pretty good roster with talented players. I feel like they weren't giving their best against F4Q either (maybe copium). Sentinels should still be clear winner here, but even 80% is really good.
Yeah 100 Thieves vs Gambit is hard one to call. Gambit has habit of struggling under pressure and this game is just that. Strong opponent, winner makes it to playoffs, whole NA vs EU pressure etc. I actually predicted 100 Thieves to win over Gambit. But, I got more confidence after yesterday even though CR was weak opponent. I think it comes down to sides as well. Gambit's defense is S tier, but their attack has always been rather weak.
