SBW excited to take field

Sonny Bill Williams might have been included in the World Cup squad for his x-factor but now he has returned to the All Blacks' fold he has been told to tone down his on-field extravagance.

Williams has had a welcome boost with his selection at second five-eighths against Tonga, following his non-selection for the final Tri Nations match in Brisbane amid news of contract wrangles.

Incumbent second-five Ma'a Nonu moves out one to centre, replacing Conrad Smith, with the selectors naming two power players against what will be a physical and fired-up Tonga at Eden Park tomorrow night.

There is no doubt Williams is excited about the opportunity - he said the "e-word" about 10 times in two minutes at the team announcement yesterday.

Perhaps a little more surprising is the fact Graham Henry and Co have talked to Williams about scaling back his adventurous play when that is what got him into the squad in the first place.

World Cups are traditionally based around defence and Williams is one player who can unlock the tightest of screens with his offloads.

"It's just more fitting into the team role, the team play," Williams said. "I guess I'm just toning it down a bit. Sometimes I get a bit too excited out there on the field."

Henry's message to Williams was clear. "Don't try and do it all in five minutes. The game lasts for 80. He played pretty well in South Africa, I thought, but I think players are inclined to, when they get a chance and they haven't played for awhile, to try to push it too much and probably overdo it.

"I guess patience is going to be key and, if he just lets his natural ability control the way he plays, I think he will play well."

Williams was confident he and Nonu would work well as several combinations had been tried at training. "Me slotting into 12 and him at 13 is no biggie. We each understand the roles."

Williams was picked ahead of Smith purely so he could have game time and the selectors are well aware of what Smith can do. Henry said Smith would return to play Japan next weekend.

"The reason was to give Sonny Bill an opportunity and he's got that," Henry said. "We don't know what's going to happen later in the tournament and who's going to be standing and who's not.

"We have to give players opportunities to play and force their abilities on the selectors. If we have injuries, guys need to have had game time in recent times."

The midfield mix isn't the only change, with Isaia Toeava and Richard Kahui on the wings, Jimmy Cowan starting at halfback and Israel Dagg at fullback.

Kahui said getting the call-up was particularly satisfying given his ongoing problems with shoulder injuries.

"To be here now in a World Cup squad and starting a World Cup game means a lot. When I look back over the last 12 months and having the operation and coming back - it's been a bit of a ride.

"My preference is still 13 but I'm very comfortable on the wing. I don't have express pace but I have other attributes: I'm solid under the high ball, my work rate and I'll chase kicks until the 81st minute."
