The Nelson Mandela Bay Stadium will be their audition arena, where performance rather than hope should be the arbiter. Especially for Dagg and Toeava, who are two players involved in the most monumental tussle for places in the World Cup back five.
The selectors have chosen eight players for those test duties this season whom they have to distil into five picks for the World Cup. Mils Muliaina is a certainty; now pick four others from Dagg, Toeava, Hosea Gear, Zac Guildford, Cory Jane, Ben Smith and Sivivatu.
The All Blacks are spoiled for choice in most positions for the World Cup though as everyone knows that does not equate to success.
There will be a number of players who will be grievously unlucky to miss the cut.
Richie McCaw is top drawer as a skipper and player while his Springbok and Wallaby counterparts do not measure up as strongly.
Bok leader John Smit is a quality leader whose legs and frame do not match his brain's commands, while Ricky Elsom does not appear to have grasped the playing or leadership mantle this year with the Wallabies.
You have to wonder whether, if the Wallabies come second tomorrow to the Boks, Robbie Deans might consider a change to Will Genia or James Horwill.
