I agree with Jake White to be honest.
You can't have a strong domestic league when selecting overseas based players, especially if your domestic league doesn't have the money to be as competitive. Selecting overseas based players seems particularly beneficial as you get your Fourie du Preez and Guthro Steenkamps. But what is in it for Tendai Mtawarira in staying in South Africa? Why does he not go and play in Japan for more money and less work? And when he goes and Steenkamp and Mtawariria are the two starting LH props for South Africa, whats keeping Coenie Oosthuizen leaving? We are already seeing South African scrum halves having to get permission from their clubs to play half of a tournament.
Saying "Why should we then devalue the Springbok jersey by not picking the best, and only select local players?" is all well and good - but I think devaluing the jersey is exactly what you do by allowing clubs to dictate who is avalible to you and when. Picking overseas based players is only a short term solution to an inexistant problem - what will become more of an issue is when the Springboks domestic league and professional teams no longer have their best players because they are making more money in France - a move which is fully encouraged by the policy of selecting over seas players. And then when clubs deny access to players, or the team isn't given sufficient practice time prior to the Rugby Championship because it clashes with NH seasons, will you be feeling sufficiently proud of the jersey? Also - South Africa will never be able to pay local players more than foreign players - at the end of the day if I'm getting $1m a year in a French club and getting paid 100k by SA - then who gives a crap if a local player has a contract with SARU for 250k-300k?
New Zealand suffers as much if not more than anyone. Since 2007 we've lost to overseas based clubs (off the top of my head) -
John Afoa, Carl Hayman, Greg Summerville, Neemia Tialata, Anton Oliver, Ali Williams, Chris Jack, Jerry Collins, Sione Lauaki, Chris Masoe, Jerome Kaino, Adam Thomson, Rodney So'oialo, Byron Kelleher, Nick Evans, Luke McAlister, Aaron Mauger, Isaia Toeava, Joe Rokocoko, Doug Howlett, Sitiveni Sivivatu, Rudi Wulf, Tamati Ellison, Mike Delaney, Mils Muliaina, Daniel Braid, Hosea Gear, Rico Gear, Jimmy Cowan, Casey Laulaula, Richard Kahui, Rene Ranger, Stephen Donald, Alby Mathewson, Isaac Ross, Lelia Masaga, Aled de Malmanche, Anthony Tuitavake, Scott Hamilton, Benson Stanley, Sonny Bill Williams.
That's over 40 players, I'm sure there are more. What's more a number of them were some of the best if not the best in the world at their position. Would we have benefitted from being able to select Carl Hayman at prop? Sure, except we'd never have given Owen Franks a shot - and he wouldn't be in New Zealand anyway. Teams like NZ and South Africa are the best in the world because the domestic competitions and super rugby teams are full with first class players. They wouldn't be as strong if they all left and neither NZ nor South Africa will have the depth. Yes players play within professionalism, however selecting overseas based players is just bad buisness. Also, how do you compare the form of a player playing in Japan - to a player playing in SR? Do you just got with the guy in Japan because hes performed before?
