I've always wondered why the comeback counts towards his mental toughness and the fact that he became a meme in the first place on the back of him consistently crumbling under any sorts of pressure doesn't. He does deserve the credit for doing what he does now but I wouldn't say that he has an exemplary mentality after what I've seen of him previously.but he obviously does have the mentality. To come back from being an absolute meme, with all the fans slating him and put in the strong performances he has done this season is something to be commended.
To be perfectly clear I'm not responding to just your post, it's more or less of a general consensus here that I don't fully agree with.
