What is the team news?
New Zealand:
All Blacks selectors have taken a massive gamble by naming fullback Jordie Barrett and midfielder Ngani Laumape to make their first Test starts in Saturday's decider against the British and Irish Lions.
While New Zealand's forward pack is unchanged from last weekend's second test, won by the Lions to level the three-test series, the backline is reshaped by three personnel and one positional change.
Barrett, brother of first five Beauden and lock Scott who are also in the match 23 for Eden Park, has been handed a debut in one of the toughest tests the All Blacks have faced in recent years. He starts at fullback, while Israel Dagg moves from that position to the right wing, Julian Savea returns on the left wing and Laumape starts a test for the first time at inside center.
New Zealand: Jordie Barrett, Israel Dagg, Anton Lienert-Brown, Ngani Laumape, Julian Savea, Beauden Barrett, Aaron Smith; Kieran Read (captain), Sam Cane, Jerome Kaino, Sam Whitelock, Brodie Retallick, Owen Franks, Codie Taylor, Joe Moody.
Replacements: Nathan Harris, Wyatt Crockett, Charlie Faumuina, Scott Barrett, Ardie Savea, TJ Perenara, Aaron Cruden, Malakai Fekitoa.
British and Irish Lions:
The Lions named an unchanged starting lineup and bench. Coach Warren Gatland said he was eager to reward those players who had taken part in the second test victory.
Liam Williams, Anthony Watson, Jonathan Davies, Owen Farrell, Elliot Daly, Jonny Sexton, Conor Murray, Toby Faletau, Sean O'Brien, Sam Warburton (captain), Alun Wyn Jones, Maro Itoje, Tadhg Furlong, Jamie George, Mako Vunipola.
Reserves: Ken Owens, Jamie McGrath, Kyle Sinckler, Courtney Lawes, CJ Stander, Rhys Webb, Ben Te'o, Jack Nowell.
Three memorable series finales
1. NEW ZEALAND 14 BRITISH AND IRISH LIONS 14 (Eden Park, Auckland, August 14, 1971)
The Lions arrived in Auckland with a 2-1 series lead, but they had no intention of sharing the spoils and wanted to secure outright glory. New Zealand made a lightning start, scoring eight points in as many minutes, yet the tourists responded impressively through a Peter Dixon try, while Barry John kicked a penalty and conversion. The game moved to 11-11, then Lions full-back JPR Williams booted a stunning 45-metre drop-goal to edge his team in front. And although the All Blacks landed an equalising penalty, the Lions did enough to claim what remains their only Test series triumph against the All Blacks.
2. AUSTRALIA 18 BRITISH AND IRISH LIONS 19 (Sydney, July 15, 1989)
The Lions looked down and out when they lost the first Test Down Under, but they tied things to set up a decider that will be remembered for Wallabies wing David Campese's defensive howler. Full-back Gavin Hastings' three penalties were the Lions feature of a tied first half, but Campese then inexplicably lost possession near near his own line, and Ieuan Evans pounced to score. Two more Hastings penalties took the Lions clear, and although Australia hit back through two Michael Lynagh strikes, the tourists held out. It was only the second time in history the Lions had fought back from 1-0 down to win a series.
3. AUSTRALIA 16 BRITISH AND IRISH LIONS 41 (Sydney, July 6, 2013)
The Lions ended a 16-year wait for a series success as they demolished Australia in spectacular fashion. The opening two encounters had been tense, tight contests, but the Wallabies were simply blown away as their opponents scored three tries in 12 second-half minutes through Johnny Sexton, George North and Jamie Roberts to give the Lions their highest points total against Australia, New Zealand or South Africa. It was the first time the Lions had a won a Test series since they toppled the Springboks in 1997.
What are they saying?
Tadhg Furlong:
"I am incredibly lucky," said Furlong, who played in Ireland's first victory over the world champions in Chicago in November and in the Lions' 24-21 win on Saturday in the second test in Wellington.
"I looked back at when we were playing New Zealand in Chicago and there are a lot of people who played the All Blacks five or six times and never won.
"I'd never played them and ... to beat New Zealand in my first game of playing them, having known that so many players ... legends of the game, had never beaten them you feel lucky, privileged.
"To do it twice, even more so."
Ian Foster:
"That is the beauty of these sort of games where it is a deciding Test. You know there is a lot at stake and everyone is trying to impose themselves physically, and it is whether you are smart enough to control that and be effective with it.
"It is something we work hard at.
"We have to make sure we are totally under control, but bring the physicality. The two Tests have been quite noticeable - one we won that battle, and one they won that battle. It shows how important it is.
"We probably didn't do a good enough job when we went down to 14 to make sure our mindset didn't narrow, and I think that it did. There was still some clear stuff for us to go to, and probably our vision was a bit narrow.
"That is not something natural for us, but we allowed ourselves to get into that sort of mode. For 45 minutes and a man down, that mode was working pretty well for us, but when we needed to see things a bit differently we probably took too long to do that."
Warren Gatland:
"It is not very often on a Lions tour that you get to pick the same 23 for the following game," Gatland said. "We felt we should reward the players for the result and the courage that they showed in coming from 18-9 down, digging themselves out of a hole and then finishing strongly in that last 10 to 15 minutes.
"We are all aware of how big this game is and we are expecting a backlash from the All Blacks. But the pleasing thing about the second test is just how strong we were in the last 10 or 15 minutes in terms of energy and enthusiasm, so we still feel there is another level in us."
What are the betting odds?
All Blacks - $1.25
Lions - $4.10
Draw - $17
What is our prediction?
Even if the Lions resist an All Blacks backlash in the early stages, holding on for a win would need a titanic effort from the tourists. Expect New Zealand to break hearts with a one-score win.
