To be honest it looks more like defending like a centre who happens to be in the outside channel, and attacking like a wing for England, JJ uses the 13 channel, and whilst Daly does look for work, for me he plays like a wing for England and I think EJ is just talking some fancy stuff to justify a selection or to confuse his beloved press.
I'm not sure if there is a way to defend like a wing - looking at Wade, he is often positioned inside another player on defence (least he was last weekend) almost like in the 13 channel
There again, having played most of my career as a prop......I might be under/over thinking this
For Wasps, I am more than happy that Daly plays in the 13 channel, similar for de Jongh, now he has settled in, similar offers in that channel for me!
