It may, it may not but I'd take it seriously. And even if it flops there will be another idea along soon.
We've already seen peak years players give up on the international game for money whether ABs through Japanese sabbaticals or English players going to France. Short career, concussions, one injury away, other sportsmen getting paid far more etc, you can understand the temptation to cash in.
The ABs are exploring the possibility of playing in the Middle East and Beaumont recently said that going there was inevitable as the sport needed the money. At least he was honest enough not to BS people about growing the game.
I suspect that the only certainty is that the next 10 years will probably see more changes in the game than the previous 120. But that's what happens when the money men get involved. Invite them through the door at your peril, as make no mistake, they don't give a **** about anything other than sweating the assets to make short term money.
