I don't get this argument that the Tahs are 'the best side on paper'.
At this moment, there are only two Tahs likely to be in the run-on Wallabies side (Foley & Hooper) and neither of them will be there if you take any notice of half the posters on this site. Then maybe (and only maybe) Simmons, Kepu, Phipps and Hunt on the bench, but again none of them are any better than a 50% chance. I am a rabid Tahs fan, but I get a bit sick of the 'they should be winning because they are stacked with Wallabies' talk.
Contrast that with say the Brumbies, with Sio, Faainga, Ala'alatoa, Arnold, Pocock and Kuridrani all likely starters, and Slipper, Powell and Banks all realistic chances for the bench, it makes some of these claims pretty unrealistic.
Sometimes, just sometimes, experience counts for more. In a world cup year it certainly does for the Wallabies.
There are a lot of good players.
I used to punt every SA player for example. SP Marais of the Stormers was one not too long ago (2-3) years ago. I have realised he is no better than average at best.
Sometimes as spectators we do not realise the intricacies such as current ability v potential ability and also what it would take to get the potential ability out of said player.
Furthermore, as Jake White recently announced on alloutrugby.com, we do not realise that every rugby player is a person, and some of them may be c*nts, or they may not even like one another. It takes a lot more than just game plans and all of that. If I don't like you it's hard for us to play together even though we may love the same team since we have grown up.
Even if you suspect ability, you may be completely wrong too.
Coaches get it wrong all the time. It does not make them bad people or bad coaches. It is a tough and thankless job and you better be willing to have your kids ridiculed at school (in SA anyway) if you are a coach.
Jake for example mentioned the accomplishment he felt when he brought a nation of varying ethnicities together and how much of a challenge it was. Do not for one moment think it is really any easier in any other country. Maybe only very slightly easier, and that only to someone who knows the landscape in the country.
It is incredibly difficult for a foreign coach to mastermind a RWC challenge based on my readings and observations - even more so if there are natural language barriers.
That is probably the reason we are not likely to see a foreign forwards / lineouts coach in SA any time soon (same for France I would imagine). Calls are taught in Afrikaans from grade 1.
