Vaea is not in the senior squad and will only get a chance through injuries.
This is usually true. There used to be a protocol that squads should have only so many contracted players but that they could use players outside the squad if there was a long term injury. The intent was to deter Super teams from warehousing players in in too large squads. This gave other teams a better chance to acquire quality fringe players and it also enforced financial prudence.
This was tied up with the RUPA agreement and IIRR this terminated in 2008 and has not been renewed. Rugby journalists like Rupert McGuiness have mentioned that there is still a limit to the number of contracted players in a squad but I'd like to see that in some official communication as it seems like Rafferty's rules prevail. According to Noddy's sticky one team has 35 contracted players and another has 29. One can always have fewer but 35 seems too high.
I have perchance digressed. Teams are going outside of those old protocols now. For example: Tahs lock Kane Douglas was used from the bench in the first game of the 2010 S14. He was an academy player and contracted players Thomson and Roodt were not injured IIRR but were ignored on form. Douglas started in all the other 13 games whereas Thompson and Roodt had only 4 games from the bench between them for the whole season. Another Junior Waratah, Patrick McCutcheon had 3 run-on games for the Tahs when Alcock could have been used, and even Lochie McCaffrey got some minutes in one game when contracted Tahs were available.
There would be similar stories in other Super teams; so if Vaea has good form in the trials or later for the Runners, and others don't, or they stumble during the tournament, he could find himself on the park in 2011.
But this all supposes that Vaea is in the next tier. There have been a few posts in this thread about who is in the next tier of players or the 2nd tier but as usual the Brumbies are slow out of the blocks on their web site. Makes a few calls Brumbies fans - give them hell.
