Instead of pointing out what stats miss, you could concentrate on what they do reveal.
I have never claimed stats tell the whole story, but they give an objective view on what is happening on the pitch, rather than the, wholly, subjective view you seem to favour.
Dismissing stats in the way you seem to means you are missing a big part of the picture, and you are always going to be called out on that where stats don't support your view. Fo example, we can't score against a low block is just not true. That we can struggle at times against a low block is true, but all teams do to one extent or another.
Had we scored in-line with our xG we wouldn't even be having this conversation, thats not something Carrick can do much about. Strikers miss chances.
I am not really interested in having a conversation about leadership. No metrics, doesn't really interest me, it's a pointless conversation. It can be interesting, but it will never go anywhere.
