To get a better handle on how this would look -
In 2012, we sent 42 players to SA. 23 forwards and 19 backs. It seems unlikely we'll send less to NZ.
A positional breakdown gives us
3 looseheads, 3 tightheads, 4 hookers, 6 locks, 5 flankers, 2 8s
3 SHs, 3 FHs, 5/6 centres (3 ICs, 2/3 OCs) 4/5 wingers, 3 FBS - mild confusion as to whether George Lowe toured more as winger or centre.
The proportions could change - less locks, more props would not surprise anyone - but if we assume these numbers that means, with everyone fit, our squad looks something like this:
Corbs, Marler, Mako (Mullan)
Cole, Wilson, Thomas (Wilson)
Hartley, Youngs, Webber, George (Ward)
Launchbury, Lawes, Parling, Attwood, Slater, Kitchener (Kruis, Stooke)
Robshaw, Wood, Croft, Johnson, Kvesic, Morgan, Billy (Clark; Dickinson)
Care, Dickson, Youngs (Simpson)
Farrell, Ford, Burns (Myler)
Twelvetrees, Eastmond, Barritt, Tuilagi, Burrell (Hill, Joseph)
Wade, Yarde, May, Nowell, Ashton (Rokodugni)
Brown, Foden, Goode (Miller/Tait)
But no injuries, well that's balls, so I've included the next men in line in brackets
So... a worst case team maybe looks like this, assuming a Sarries/Saints final
1. Catt 2. Ward 3. Collier 4. Matthews 5. Myall 6. Fearns 7. Wallace 8. Ewers; 9. Robson 10. Cipriani 11. Varndell 12. JTH 13. Daly 14. Sharples 15. Miller/Tait; 16. LCD/Yeandle/Buchanan 17. Wood 18. JCW 19. Robson 20. Haskell 21. Lewis 22. Slade 23. Watson
That's not a bad team tbh, if a little raw up front, but no cohesion and really fit for A team duty. Sending them against a full bore Baabaas side, well...
Reality is we'll probably even see some guys from the level of depth below that tbh, particularly if one of Leicester or Bath reach the final, which, after a quick think, means these guys...
Harrison, Buchanan/Yeandle/Taylor, Sinckler, Barrow, Kennedy, Garvey, Seymour, Gaskell/Jones, K. Dickson, Carlisle, Thompstone, Allen, Hopper, Smith, Pennell
In fairness, not too many players there I'd be worried about in a strong team.
