One good answer to this question is: if a team is instructed to play through the flanks, then it is likely that the players on the flanks will be more active. That is a possible reason why wingers score more goals than strikers in wing formations like 4-5-1(V).
But then, we expect the wingers to cross it in. But again AMs shoot more often than pass it.
