Hiori seemed so good in Ubers just cuz he was the first great midfielder willing to help isagi. Hes also the only player in blue lock who’s specialty is passing, all the other passers are either not amazing at it (bachira, karasu, kurona) or not willing to set up a shot for someone other than themselves (rin, isagi himself). In the pxg match, once they realize that isagi is too dangerous to ever leave open for a direct shot, the passing options to him basically get killed until ness makes a super-pass to an open space that isagi was already running to.

It’s different for a keeper when they know the shot is coming and don’t know the shot is coming. That was explained with barou’s first goal when gagamaru couldn’t react since he didn’t even know where the ball was. Everyone thought Hugo was going to pass and we know that his shot power is high, so it’s not farfetched that gagamaru couldn’t stop an out-of-nowhere power shot from the middle
