If Son cost us 2 or 3 goals a season, and very nearly many many more though it would be an issue.It doesn't overshadow the rest of his attributes though. He's just bad at kicking. Same way Son can't tackle. It doesn't neutralise the rest of his makeup.
Hugo's kicking is far from a non issue in my opinion. Brilliant keeper and character, but his sweeper keeper role is non existent anymore. I'm guessing that's because Poch has abandoned it.
