Smith is an absolute outlier.
Where most players find they have technical problems, they go away and work to resolve them.
Smith goes away and works out how to score runs despite them. He still plays away from his body horribly, and open the face in a way that would scream tail end in normal circumstances. But...he has learnt how to leave the ball, so the former is less of a problem, and uses the latter to play half-defensive shots that score, so it becomes a strength.
