I've never understood this. Every tournament I've ever been involved in has had the two top rated refs from the preliminary games do the semi-finals, with the best performer there getting the final and the other the AR1 spot (with the best performing AR from the semis getting the AR2 spot).
Obviously in a WC this isn't always possible due to countries being involved but I don't know why you would sit your supposed best ref out of the semis and give your number 3 a game? With a week between games it's not like injury is a realistic issue?
My thoughts exactly mate. Of all the sports I know enough about, union is the only one which does this. Some on here have argued that it gives others "experience", but considering the next World Cup isn't for another 4 years, a semi-final now is not going to mean anything by then.
The four teams deserved the best two referees (presumably Owens and Garces). If the 3rd best ref had a major f**k up, the whole system would look very, very stupid.
Even without a major cock up, it could be argued that Barnes' performance was not good enough for a World Cup semi, and there is little doubt that Owens would have been better.
