This post is more specifically addressed to the likes of ppl like Slothfield, Fitzsimmons etc. who continually bag international RL. Ok, the crowds may not be as large as the ones Union get for internationals and the crowd growth potential may not be as large as the one that turned out in Chicago to see the All Blacks, but this year's tournament has been far more exciting the the Rugby Union four nations, and it bodes well for the 2016 four nations in the Northern Hemisphere as well as the potential to expand it to a five nations (the other team being the winner of the European Cup to join the winner of the Pacific Cup and the big 3).
The good thing so far about this year's four nations is that going into the last round of matches in the qualifying phase, all 4 teams are still in contention to either qualify or miss out on the final. Being on 4 competition points, NZ have the best chance of making the final. A win, draw or loss by LESS THAN 9pts against England will be enough to make the final. A loss by 9pts or more will mean England overtakes NZ on F/A and Australia can eliminate NZ from finals contention with at least a 25pt win against Samoa (in the best case scenario for NZ where England wins by 9pts, requiring Australia to win by the maximum number of points needed to overtake them).
For England, a win by 9pts or more gets them into the final. A loss opens the door for Australia and Samoa, and a draw opens the door for Australia. A win by 8pts or less means Australia will have to win by 17-24pts against Samoa to eliminate England from finals contention.
For Australia though, the most difficult route for them to qualify will be if England beats the Kiwis by 9pts. In that case, Australia will have to beat Samoa by at least 25pts to make the final and given Samoa's form this tournament, that outcome is definitely no guarantee (even though an Australian win is most likely though).
For Samoa, they need NZ to beat England to have any chance. If England wins or draws, Samoa is out of contention to make the final. The most difficult route for Samoa to qualify will be if England loses by 1pt, in which case Samoa will need to beat Australia by at least 9pts to make the final.
In summary, I'm really looking forward to this weeks' matches. All teams have something to play for this time around, compared to the previous 4 nations tournaments where the 4th team - PNG and Wales were just making up the numbers. Samoa have been vast improvement on the 2010 PNG and 2011 Wales campaigns and with more matches and game time to try and improve combinations and capitalise on missed opportunities, Samoa remains the biggest threat to the big 3, and the best chance of all the countries outside of the big 3 to make the 2017 RLWC final. Regarding the four nations tournament though, the bottom line is that the result and margin from Saturday's NZ vs England match will be crucial on who makes the final.
