There were some positive signs for us yes (though not many), but if I was Ricky Stuart I would not be happy at all with Saturday's game despite getting the win.
When a makeshift team with around half of it reserve grade quality can put 30 points on a top 4 team there is cause for concern. With defence like that the Raiders will be cannon fodder for Melbourne, Cronulla, NQ or Brisbane in the finals. And at least 5 of Canberra's 8 tries came directly from Manly errors, either handling or defensive, and I can't see any of the four teams I mentioned gifting them that many points.
Take a look at the team we put on the park on Saturday. Wiliame, Wright, Parker (only because of age and lack of experience), Starling and Winterstein would struggle to get an NRL game with just about any of the top 8 teams while AFB, Brown and Koroisau might get onto the bench for any of them but they definitely wouldn't start. That's 8 out of 17 (6 of whom were in the starting 13) who I wouldn't even put in our strongest 17 if players weren't out injured, and I doubt they would be there for other clubs either.
