Pickford's stats say otherwise, though. Constantly at the top or near the top in most.

I think there are a few factors at play with Pickford: at Everton, he's frequently involved in the play and that plays to his strengths - long periods of concentration possibly not his forte; he's also erratic in terms of his distribution at times which seems oddly more important than actual 'keeping; most importantly, he seems genuinely happy at Everton and that's really important to him.
