Listening to Hudson on Radio sport makes me a little less concerned about how useless he is. Aware of the mistakes we made v Japan and other nations recently. Realises the affect this game will have and how important having a loud vocal crowd.
I'd say since USA tour last year (Mexico & USA friendlies) the squad has been pretty much the same. Only recent experimentation comes to mind is Ingham, and Bevan plus reserve keepers Sail/Woud (who never played). Happy to be corrected.
The actual 1st eleven will always change somewhat, subject to player availability/injury and form. To not experiment to a point, and build depth would be plain stupid.
More important thing is that core of squad, have been playing together for awhile now, and nearly all have 10 plus caps. This alone is an improvement on the same stage in 2013, when Herbert was making all sorts of last minute changes/weird decisions.
