Tieba users have long put the blame on Ito for losing to Solja at Rio 2016, instead of Fukuhara when both of them lost 2 matches (singles and doubles).
Minnie has been praised as the heroine for beating HY and SXN at Tokyo 2020. If she lost either, chances were LHC was going to lose the 5th.
The common denominator here is the youngest player on the team, the make-or-break player per se. Like for TWC 2019, Hirano had to step up and beat JJH in the 3rd, as she couldn't rely on Ishikawa to finish the job in the 5th.
Likewise, KOR's loss was pretty much sealed when SYB failed to step up and beat HY in the 4th, hence "their best hope" in my previous post.
