If we’re talking stats I can confirm that all shots that are blocked successfully have an xG of zero so until we talk about conceding close to the most amount of goals in the league, shots are irrelevant.
Also your first sentence is very silly, if you don’t know what I’m saying how can you say it’s wrong.
It’s my belief that you are wrong saying that conceding shots that are blocked is bad defending. In fact, next time one of our defenders blocks an effort look out for Pickford giving them a little low five which happens regularly because they’ve done some good defending.
