15. Fullback
Leigh Halfpenny - Wales
Honourable Mentions: Israel Dagg (NZ), Ben Smith (NZ)
Leigh is a hero. No other word describes him quite as aptly. A man, not great in stature nor physicality, but willing to give everything to the cause, to sacrafice everything if it means Wales might scrape a win. Look at him knock himself unconscious twice in one season making tackles that could have saved the game in the last play. He's also got the spirit and mental steeliness to kick goals under any amount of pressure. Best kicker in the world. Best fullback in the world.
14. Right Wing
George North - Wales
Honourable Mentions: Tommy Bowe (IRE), Alex Cuthbert (WAL)
In years to come, geography students studying the unit on forces of nature, normally reserved for hurricanes, tornados and tsunamis, shall be looking closely at George North. An unstoppable force yet to meet an immovable object, he's got absolutely everything you could want in a winger. Power, pace, good feet, good hands, the ability to finish and, most importantly, a brain. Incredible.
13. Outside Centre
Conrad Smith - New Zealand
Honourable Mentions: Jonathan Davies (WAL), Manu Tuilagi (ENG)
The archetypal centre. Doesn't miss tackles, makes breaks, links well, runs good lines, offers supporting angles. You couldn't ask for more than what you get from Conrad Smith.
12. Inside Centre
Wesley Fofana - France
Honourable Mentions: Ma'a Nonu (NZ), Jamie Roberts (WAL)
Fofana is the best centre I've seen since O'Driscoll on the top of his game. He sprints through gaps that aren't there, and is always able to finish whatever he starts. He averages a try every other game for France, and in two of his caps he received less than 3 touches of the ball. He's amazing.
11. Left Wing
Bryan Habana - South Africa
Honourable Mentions: Julian Savea (NZ), Digby Ioanie (AUS)
He's still got it. Time was, I, along with seemingly everyone else, felt King Habana was past it. Overtaken by a barrage of youthful imposters. How wrong we all were. Bryan Habana still has what it takes to unlock defences the world over, and he's about to do so for rugby's own free-vending ATM, Toulon.
10. Fly Half
Dan Carter - New Zealand
Honourable Mentions: Aaron Cruden (NZ), Dan Biggar (WAL)
Oh come on, who else was I going to pick?
9. Scrum Half
Will Genia - Australia
Honourable Mentions: Kahn Fotuali'i (SAM), Aaron Smith (NZ)
Another no-brainer. Genia is sharper the worlds' best-trimmed set of pencils. Also hard to read as lead in a radiation scanner (That was tenious), hence why defences consistently struggle to close him down. He was the cause of any struggles the Lions had last month. One of the worlds' very finest players.
1. Loosehead Prop
Alex Corbisiero - England
Honourable Mentions: Thomas Domingo (FRA), Gethin Jenkins (WAL)
A dominant scrummager and a real handful in the loose, Corbisiero is a perfect blend of a proper prop and this kind of new dynamic thing Sky Sports and Stuart Lancaster both seem to love (Joe Marler, Cian Healy, whatever). Really improved his credentials on last months' Lions tour.
2. Hooker
Bismarck du Plessis - South Africa
Honourable Mentions: Andrew Hore (NZ), Tatafu Polota-Nau (AUS)
A player so good he forced his national captain to learn a completely new position in his thirties. Du Plessis is a handful in the scrum, a key cog in the best lineout in the world (Sorry Scotland) and full of enough beans to keep him bounding about the pitch, making tackles and carries for the full eighty.
3. Tighthead Prop
Adam Jones - Wales
Honourable Mentions: Nicholas Mas (FRA), Dan Cole (ENG)
I support Wales and the Ospreys, and I hate to think how many victories I've celebrated over the last five years would not have occurred had Adam not been playing. An unstoppable scrummaging force; bend over and push. That's a props job, and Adam does it better than anyone else in the world, and long may that continue.
4. Second Row
Paul O'Connell - Ireland
Honourable Mentions: James Horwill (AUS), Richie Gray (SCO)
There is no stopping Paul O'Connell. The man is a creature made of living concrete, unable to be stopped, harmed or destroyed. He goes until every inch of the magic beans used to turn him into a living creature is used up, at which point he returns to his more familiar statue form. The inspiration for the Weeping Angels. They had to be toned down in the scary stakes for a prime time audience.
5. Second Row
Alun Wyn Jones - Wales
Honourable Mentions: Eben Etzabeth (RSA), Sam Whitelock (NZ)
A team of fifteen Alun Wyn Joneses would win any World Cup. Not even just in rugby. Alun Wyn is the most driven, hardworking player anyone is likely to ever watch. He's a machine with a heart. The pride, the passion of representing Wales, the Ospreys and the Lions is so evident, and he more than lives up to it every time he takes the field. Hero.
6. Blindside Flanker
Dan Lydiate - Wales
Honourable Mentions: Sean O'Brien (IRE), Willem Alberts (RSA)
The most difficult position. Were I selecting a XV to play Mars, I'd shift Lobbe, Parisse, Warburton or McCaw across. However, I'm picking the best in each position in the world, and nobody fulfills a No. 6's job better than Danny Jonathan Lydiate, a farmer from east Wales. Makes a stupid number of tackles and misses very few.
7. Openside Flanker
David Pocock - Australia
Honourable Mentions: Richie McCaw (NZ), Sam Warburton (WAL)
Nobody else in the world is quite as destructively efficient at the breakdown as David Pocock. Every ruck, he either turns the ball over, or costs the attacking team two or three forwards in clearing him out. He also links superbly. The engine of McCaw and Warburton and the skills of Tipuric cannot, however, be underappreciated. Such a difficult position to select, but Pocock nicks it, just. JUST.
8. Number Eight
Kieran Read - New Zealand
Honourable Mentions: Sergio Parisse (ITA), Juan Martin Fernandez Lobbe (ARG)
Lobbe. Parisse. Picamoles. Faletau. Morgan. Heaslip. Spies. There are more world-class players in the number eight position than any other, so it'd have to be a pretty special player who sits proudly atop them all. Read is just that. For my money, at the moment, the very best player in the world. There's nothing this man can't do. Every game he plays is a masterclass in not just backrow play, but rugby in general. He lords it over the whole pitch. A colossus of the modern game.
