1. Benn Robinson:
One of those clever props who mix a highly-developed survival instinct with a crafty approach to the set-piece duties. Excellent in open field, but could be dominated at the scrum.
2. Stephen Moore:
Life in the Wallaby scrum is not always fun and the hooker has suffered for his art. Still one hell of a competitor. Just possibly beyond his prime.
3. Ben Alexander:
Like Robinson, he tends to do a job on mean, nasty front-row opponents when least expected. A fine player at this best, but his best can be elusive.
4. Kane Douglas:
How the Wallabies must yearn for Nathan Sharpe. Better still, John Eales. The engine room is a problem for them and while Douglas is big, he is profoundly inexperienced.
5. James Horwill:
The captain may be the most important single individual in the side – not because he is a world-beater, but because only he can hold this pack together. If he misfires…
6. Ben Mowen:
Another newcomer, although no one watching the Brumbies in Super 15 will doubt his capacity to deliver. Once seen as too passive, his physicality now matches his line-out expertise.
7. Michael Hooper:
No Pocock or Smith, but the Wallabies have more star breakaways than New Zealand. Hooper is fast, clever and a superb carrier, although not the most canine in a dogfight.
8. Wycliff Palu:
The strongman's return from injury means masses to the Wallabies. Their back-row unit will not be bullied while he is in situ. Punishingly physical, if not the most sophisticated.
9. Will Genia:
Probably the world's best scrum-half and the Wallaby heartbeat. No particular downside, so if the Lions fail to cramp his style, they can expect to lose.
10. James O'Connor:
The only one of the "terrible trio" to start: Kurtley Beale is on the bench, Quade Cooper nowhere. Has all the X-factor imaginable, but is he really a Test pivot?
11. Digby Ioane:
A high-value wing and a stand-out at the last World Cup. No obvious weakness, but may be short of a gallop after injury.
12. Christian Leali'ifano:
New man in midfield. Would have faced Wales last year but for injury. Heavy scorer but will he freeze on debut?
13. Adam Ashley-Cooper:
Some question the his net worth, but European clubs would pay a mint for an outside centre of his quality. No Billy Whizz, but dependable and ruthlessly competitive.
14. Israel Folau:
The new sensation in Australian union, having already been a sensation in rugby league. New to the complexities of the 15-man game, but has all the physical gifts.
15. Berrick Barnes:
A game-shaper of great subtlety who will use his outside-half skills at first receiver. Neither the most robust nor the most consistent, but dangerous.
1. Alex Corbisiero:
A Test starter from outside the original squad, although he would have been picked in the initial 37 but for injury. Technically sound and highly intelligent. Has he played enough rugby, though?
2. Tom Youngs:
The low-slung hooker who has scaled the Test mountain in six months flat. Hard-bitten, relentlessly competitive and blessed with a centre's hands, his one weakness is his line-out throwing, which has been a problem on this tour.
3. Adam Jones:
They say Test-quality tight-head props are in a seller's market, so the Welshman can ask for the earth. The best scrummager in the world and clever with it. Pretty much priceless.
4. Alun Wyn Jones:
If he shows up – and my, how he showed up on Grand Slam day in March, and again in Sydney last weekend – he is a piece of work. Inconsistent, but necessary
5. Paul O'Connell:
A middle name of Jeremiah does not fit with the grand Irish lock's optimistic, can-do approach. On the downside of his career at 33, but still a proud, pulverising force of nature.
6. Tom Croft:
No longer the "luxury pick" of old, but he is by a distance the quickest Lions forward and he couples this with being the best in the air and increasingly rugged at close quarters. Can he stay in one piece?
7. Sam Warburton:
Major-league tackler, brilliant turnover specialist… but is the skipper really at his best? If not, he will have his hands full cramping the style of the Wallaby loosies.
8. Jamie Heaslip:
A more rounded footballer than his rival Toby Faletau, the Irishman's recovery from a rough Six Nations has been striking. On a good day, sensational. On a bad one, subdued.
9. Mike Phillips:
The polar opposite to outside-half Sexton: if the scrum-half has vision, it is of the tunnel variety. But for brutish strength and physical presence, he is out there on his own.
10. Jonathan Sexton:
Tall and spindly with a slightly fragile air, the Irishman can bring to the Lions what Stephen Larkham once brought to the Wallabies. A creative midfielder with a visionary streak.
11. George North:
A John Kirwan for the modern age? The Independent's columnist Brian Smith thinks so. No wing his size can be great chasing back, but going forward he is seriously scary.
12. Jonathan Davies:
He might have been the best-performing Lion not to start a test, but Jamie Roberts' fitness problems changed all that. A far better player than his low profile suggests
13. Brian O'Driscoll:
The Lions' emotional touchstone. Not the player who captured the imagination here in 2001 – the turbo-charged pace has gone – but he may be even more competitive.
14. Alex Cuthbert:
One of the "Panzer" backs still standing, the Welshman has an eye for the long-range finish. But he is vulnerable on the turn and some way out of form.
15. Leigh Halfpenny:
A perfectionist of Wilkinsonesque proportions, his goal-kicking has been revelatory. He has also mastered the full-back's role with ball in hand, but will Folau strip him bare in the air?
