I'm sure that is why they do it, but I don't agree with it. Part of what I want a wide player to do is lay things on for others, which is far easier for them to do on their "correct" wing. If they're tricky enough they can also get themselves into shooting positions for their strong foot quite easily from there. If they aren't tricky enough, playing them on the left isn't going to help anyway, 'coz then they're coming infield where play is more crowded.
