Other mistake: All of a sudden and with no explanation, in this episode the coach and the cheerleading team have things like whistles and megaphones that they never brought to matches before and didn't have when the match was underway in the previous episodes. (00:05:55)
Other mistake: When Misaki gets the return passage from Teppei, his legs are skeletal, much thinner than usual. (00:11:15)
Other mistake: The play that ends with the aerial challenge between Musashi's forward and Mamoru Izawa does not make sense, since it happens in the penalty area, which would need to be enormous to allow long range passes and lengthy runs. It was meant to start in the midfield and not in the penalty box, obviously.
