The NRL is the best RL competition in the world and it is completely understandable that a player would want to go and test himself at that level. It's no different that footballers wanting to be exposed to playing in the European Champions League. The only difference is that in football there are several clubs where you can have that exposure whereas in league the exposure you can get is in the NRL.
If the forthcoming NRL television deal is anything like the value which is being banded around then the decision to go to the NRL will become easier and easier for British players. There is very little we can do about that other than continue to grow our sport at the fastest pace its finances will allow. We will have to accept that we won't be able to compete with the NRL unless SKY give us a bumper pay deal next time around and that is unlikely. If the NRL does grow significantly, perhaps we will get our wish of either a British team in the NRL or enough British players involved in the NRL to turn us into a credible international force.
