With regards to Campbell - I agree it is too early to talk of him being a Wallaby starter, although I’d like to see him in the squad.
I do find both Maddocks & Banks to be inconsistent though. If DHP is out injured I don’t think either of them have showed the sort of consistent form to demand selection. Their best is very good, but Banks has been so-so for a lot of games and Maddocks downright crap at times. I’m inclined to give Banks a bit more benefit of the doubt because his prep has been injury interrupted.
