The other thing is, if GreenEdge become option #1 for Australian youngsters coming through, then it may end up limiting them because the team doesn't suit them as cyclists, much the same way as a British rider with a skillset not suited to Team Sky may find themselves stagnating a bit. Luckily for Aussies, there are enough Aussies in the ProTour world that they have plenty of role models outside of GreenEdge; the Britons outside the Sky umbrella are few and far between. Plus, of course, in order to be seen as the key British team, Sky have almost needed to pick up all the British stars. After all, last year Britons were being asked to cheer on a New Zealander and a Norwegian in sprints, against Britain's most well-known road cyclist. It then creates the debate: Team Sky OR Cavendish - which is wanting British success more? We only need look at how Team Sky broke the bank (and the moral code) to sign Wiggins in the first place - the British team NEEDED a British contender to legitimise itself in the eyes of fans.
If GreenEdge want to be seen as the de facto Australian team (and you give the impression that they would do, in order to appeal to that patriotism that may be essential to capturing fans' imaginations) then they may find themselves caught up if, say, GreenEdge's pursuit of a sprint damages the GC hopes of Cadel Evans if he's caught behind a crash, or something like that. If patriotism is the main thing your fanbase looks at, then you can't be fighting against the best Aussie rider in the péloton!
Basically, all of these national team projects are fraught with problems. Katyusha couldn't attract Menchov, GreenEdge haven't picked up any Australian men who are even remotely GC oriented, no Evans, Rogers, Porte, nothing. Sky had to break the moral code and the bank to get Wiggins, and then had to wait two years for Cavendish. Astana are the only one that got their man (men) straight away, but that's more because they bought out an existing team, kicked out some Puerto names and Spanish youngsters and replaced them with Kazakh ones.
