Yea your gotta be joking if you think the changes of dropping Smith and Moeroa weren't made to improve us. Regardless of what stats you want to throw at us, I was there and I saw it first hand, Salmon is a much better foil for Moses and we looked better cause of it, plain and simple and hence why our attack looked much better.
It all has to do with our forwards aiming up and that determines if we win or not. But our forwards aimed up massively against Souths and we only won by what 10-12 points with Smith in the side and Moses setting up 3 tries, last night they aimed up again and we won by 28, so that tells me our halves were much better last night and that happened to have Salmon in instead of Smith.
