Sivivatu has a superb game against Fiji (Graham Henry suggested he was the best player on the park in the first half, which I agree with). If he can continue that sort of form I'd be happy to have him in the RWC squad, as he's a proven match-winner in international rugby. However I do worry a lot about his 'passive' defense - he often puts himself in great positions to make tackles, but seemed to fall off a large percentage of them during the Super Rugby season. The fact that he can't seem to go through a week without getting injured worries me too...
ALL BLACKS team: Mils Muliaina, Sitiveni Sivivatu, Conrad Smith, Ma'a Nonu, Hosea Gear, Dan Carter, Piri Weepu, Kieran Read, Richie McCaw, Jerome Kaino, Brad Thorn, Ali Williams, Owen Franks, Keven Mealamu, Wyatt Crockett.
Reserves: Andrew Hore, Ben Franks, Sam Whitelock, Adam Thomson, Andy Ellis, Colin Slade, Sonny Bill Williams.
I'm still don't like SBW on the bench, but I suppose they need to give him gametime, and the 'utility' backs (Toeava, Kahui) are still recovering from injury (maybe they should have given Ben Smith another go
)
