We don't really need to rehash this, but she had an unbelievable season and also had a brutally bad match. She also didn't seem to be rounding into form or anything, she played in 4 sets (although was benched for chunks of the last 2). What do you think the narrative would be if we played her in the 5th and had the same outcome? Probably "What kind of coach keeps going back to a player hitting .045 when her sub was hitting 5 times more effectively?"
Sure, you can argue we should live and die by our star players. But people can also argue for pivoting to another good player who was playing better. She had a heckuva season in any case, it's just a shame that her worst match will be the most remembered because it was the end of their run.
