My pre-game opinions on the named side:
Wags' strangth is his defence. Dogs danger players are Anasta, Thurston and Sherwin. This week Wags has to play a position where his strong defence can impact the games of these three.
Pack is good, hard-working. No "flair" players, but the back row guys have enough flair between them to create something if its there.
Vaealiki copped a knock in the trials, and Doggies centres are rookies, so I think Smith is using the early part of the game to have a look at how Muzza/Sideshow goes in the centres, before bringing Vaealiki on for reduced gametime to ease back in.
My only concern is how the ball will get to the backline through Wags. If they come up with another way to do it on field (eg Hopkins, Morris, Dykes palymaking trio) then great, Wags can wear the No 6. But I agree its a week to week thing, and seems imo to not be the strongest premiership winning combo there.
