What the Wallabies would give for Jordie Barrett.
Fulcrum, facilitator, hit man, there's seemingly nothing Barrett can't do.
Barrett has long been a focal figure for the All Blacks but his six-month stint with Leinster last year appears to have further elevated his world-class status.
South Africa will passionately present Damian de Allende's case but while he's a destructive class act, Barrett's influence on his teams is unrivalled this season.
Barrett isn't just displaying his qualities as the world's premier inside centre - he's firmly in the conversation for the world's best player this year.
Broadening his rugby portfolio with 15 appearances for Leinster proved an astute, invaluable experience. Absorbing contrasting styles, atmospheres, opponents and opposition has enhanced Barrett's rugby IQ - and allowed him to bring those lessons home to New Zealand.
With Ruben Love carving up the cutter, Josh Moorby and Fehi Fineanganofo scoring 17 tries each to break the single season Super Rugby record, Asafo Aumua flattening defenders, Warner Dearns commanding the air and their stacked loose forwards turning heads, Barrett's influence was underplayed as the Hurricanes claimed their first championship in a decade.
Ask anyone within the Wellington franchise, though, and they will extoll his far-reaching influence.
For the All Blacks this season Barrett's impact has been more overt. In a team that lost the Greatest Rivalry series 3-1, he was consistently the All Blacks' standout performer.
It's easy to look dominant in a winning side - much harder to shine, particularly as a back, behind a beaten forward pack.
World-class gets thrown around too readily in the social media age. One performance from a playmaker is enough to evoke comparisons to the one-and-only Dan Carter.
Barrett, though, is among a clutch of genuine elite echelon players the All Blacks will heavily lean on as they build for next year's World Cup.
Barrett, Cam Roigard, Will Jordan, Ardie Savea, the latter sidelined for the remainder of the year, are the bolted on world-class All Blacks. Fabian Holland and Peter Lakai could, in the years to come, emerge into that bracket too.
Last weekend, as the All Blacks retained the Bledisloe Cup for a 24th straight year with another dominant victory against the Wallabies, Barrett reinforced the breadth of talents with a commanding, follow me performance.
From a defensive masterclass as he walloped every gold jersey in sight, with complete disregard for his body, to outleaping Joseph-Aukuso Suaalii and laying on a try to popping up at first receiver to orchestrate the backline, Barrett was everywhere.
Codie Taylor has assumed the captaincy in Savea's absence but for pure inspiration, Barrett is leading the All Blacks.
"He's been phenomenal all year. He was outstanding in South Africa. He's taken his game to another level," All Blacks coach Dave Rennie enthused. "It's not just the skills-set but he's got a massive engine and then his physicality. He was excellent again tonight. He had a little bit of a hematoma, and we weren't sure how long he'd last after halftime, but he was able to run that off."
Barrett's imposing physical presence and 16 tackles against the Wallabies had Taylor suggesting he could feature in the loose forward ranks.
"You could probably have a 6, 7, 8 on his back and he wouldn't look out of place, he's one of those men. Of late he hasn't been saying too much, but his actions on the field are world class," Taylor said.
"He's definitely earned the right to be called probably one of the best, if not the best 12 in the world at the moment, not just through his attack, his brutality, everything that he does, he's physical, which is what you want to see as a forward when your 12 is prepared to throw his body onto everything."
Tana Umaga's presence behind the scenes, as one of the All Blacks' greatest midfielders and leaders turned national defence coach, could be another factor driving Barrett's growing impact.
Umaga isn't prone to outlandish statements but when he speaks, players listen.
Last week Umaga delivered a passionate internal sermon to remind the All Blacks of the importance of the Bledisloe Cup. That certainly resonated in their performance.
This week, after arriving in Sydney for the rematch with the Wallabies, Umaga offered his assessment of Barrett.
"I think he'll go down as one of the best we've had," Umaga said, nonchalantly.
Hard to argue with that.
Glancing across the field it must be difficult for the Wallabies to not envy Barrett's quality. At a time when Hunter Paisami is suspended, Len Ikitau is injured again, the Wallabies will be forced to dig deeper into their depleted midfield ranks.
With the Bledisloe banked the All Blacks have the flexibility to rotate their squad this week but the messaging emanating from their camp suggests there is no respite in sight as they seek to extend their 12-match unbeaten run against the Wallabies.
Barrett noted individuals and teams are judged by their consistency, not one-off results.
"I want to back them up," Barrett said of his performance at Eden Park. "We've got another challenge here in Sydney this week against a good Australian side who have a great record, particularly in Australia at home.
"We know how tough this is going to be and we've spoken about how, if we want to go to where we want to go as a team, we've got to put up back-to-back performances so hopefully we can keep our standards high.
"There's no trophy to play for but internally there's some habits and standards and a legacy that demands All Blacks to back up and represent your country. Our ambition and our goals haven't really changed."
In lieu of a clone machine the Wallabies must stop Barrett - or hope he's rested - if they are to halt the All Blacks.
