And the backs....
Scrum-Half
Grieg Laidlaw has been unfortunate to be injured at a vital point in the season. Certainly, his leadership would be valuable, but he isn't quite the quality of the other options available. Conor Murray is perhaps the finest number 9 in world rugby and will be a strong favourite to start the Test Series. His excellent kicking game will be crucial in the territorial battle. Rhys Webb continues to be an imaginative attacking threat, especially in broken field, and his form alone warrants selection. Again, there is an English shootout for the third spot. Danny Care is more similar to Webb, sniping around the fringes and always on the lookout for a gap. There are unlikely to be such spaces to exploit against the All Blacks though, and so the extra control, experience and leadership offered by Ben Youngs gets him on the plane instead.
Fly-Half
Jonny Sexton will start the Test Series at 10. He is a battle-hardened warrior who gets hit time and time again and still keeps his sides moving in the right direction. His goal kicking has also improved over the past 4 years and he would be a fine option if required in this regard. Owen Farrell has matured as a playmaker in the past 12 months to the extent that he could start at either 10 or 12 and be the most influential player on the pitch. His composure under pressure as a goal kicker is second to none and he will likely be the kicker come the 1st Test, though with 12 on his back. With Sexton and Farrell both in the Test side, a third fly half is imperative. George Ford has been influential in a winning England team, but importantly, he has had the comfort of a playmaking 12 next to him. He won't have this in New Zealand, and therefore finds himself heading to Argentina with England instead. It's a close call between Dan Biggar and Finn Russell, but Russell's attacking intent and ability to stand out even in defeat earns him the chance to make a real name for himself this summer.
Centre
Robbie Henshaw has been the form centre of the past 12 months and could play at either 12 or 13 at Test level. He can truck it up if required but also has subtlety and a clever kicking game which can unlock high quality defences. His club and country partner, Garry Ringrose, has been a revelation and could be a real bolter for the Test side at 13. His selection ahead of Jonathan Joseph may raise eyebrows, but Jospeh's best recent performances have come against wide-open Italy and Scotland defences which certainly won't be replicated in New Zealand. Scott Williams didn't have the 6 Nations he needed to be considered and Alex Dunbar unfortunately looks slightly one-dimensional to tour. There's nothing wrong with an inside-centre who is physical and runs straight lines to makes space for others, but if taking one of those, why not a man who has toured successfully before? A man who understands what it takes to be a Lion, who could lead a midweek team by example and be a sounding-board for younger players on tour. Jamie Roberts offers all of this and more, and is worthy of a place on tour with so many options in midfield. Jonathan Davies had a great tour 4 years ago but has had a poor 6 Nations. The flexibility offered by Elliot Daly, and his ability to play in so many different roles couple with his wand of a left boot, makes him a natural choice to tour, and another real option for the 13 shirt come the Test Series.
Wing
George North needs no introduction. If his form gets anywhere near his best, and he comes alive as he did 4 years ago, he will start the Test Series on one wing. The other side will be more challenging. Anthony Watson is a fine athlete, quicker than any other potential tourist, and has the ability and qualities to play at full-back if required. Jack Nowell offers a different dimension to all other wingers. He bounces off tackles like they aren't there, works incredibly selflessly for the team, and is rock-solid in defence. His potential impact on games late on makes him a genuine candidate for the 23 shirt in the Test Series. The final spot is very tricky indeed. Denny Solomona, with another 6 months in the sport, could be a brilliantly maverick choice. Tim Visser and Christian Wade are both incredibly good finishers, but neither has ever consistently delivered at international level. Sean Maitland is strong and tireless, much like Nowell, but does not have the finisher's instinct of others. Chris Ashton is close, very close. He seeks out work, he is an incredible finisher, his defence is actually better than people give him credit for. But he is shaky under the high ball. Ben Smith will be testing the Lions back three all series and therefore it is imperative for the wingers to be strong in this area. It is a long time since a winger has come out of Scotland's good in the air as Tommy Seymour. Not only does he tour, he may well start the Test Series.
Full-Back
Nowell, Watson and Daly at a push, can play at full-back, so only 2 will travel. Mike Brown has lost form and perhaps confidence recently, and Rob Kearney comes with his own injury worries. They will have to wait by the phone in case of a raft of casualties. Stuart Hogg was again a standout player in the 6 Nations, exhilarating in attack and brave from as deep as his own line. His defence will need work if he is to start the Tests but he tours nonetheless. Leigh Halfpenny was superb 4 years ago, but he has only shown patches of that form in the past 2 years and his goal kicking is now less of requirement with the improvement shown by both Farrell and Sexton. Instead, his countryman, Liam Williams must travel in his favoured 15 shirt. His rangy running style, fierce defence and eye for the try-line means he must be considered a real front-runner for the Test spot.
