Cooper and SBW may not be the last Union players to switch to the NRL.
When the new ARL TV deal and revised (upwards) salary cap comes in for 2014 there'll be plenty Union players' agents wanting some of that for their clients.
There might not be many Aussie union players as all the best talent comes to League anyway but over the Tasman there are some brilliant Union players who could adapt to League quite easily.
Then there's South Africa. Their currency, the Rand, is of very low value especially against a high value currency like the Aussie dollar. Some of them could make their way to the NRL for a slice of the Rugby League financial action.
The way it's all being talked about this ARL TV deal is really big money for Rugby League players and I can see some Union players being persuaded by it to switch codes.
