World Rugby have finally started murmuring about looking into the three-year residency rule on eligibility.
By the end of the upcoming World Cup, they should see that they have no choice but to revisit the laws and ask whether they are robust enough.
A few years ago when this topic came up, World Rugby were content that there was no issue. They agreed that it was fair and reasonable to determine that living somewhere for three consecutive years is enough to earn eligibility to play for that nation.
World Rugby felt that threshold was credible, that it reflected a significant commitment on the part of the player. But on the eve of a World Cup that is going to see significant numbers of players represent nations on residency grounds, World Rugby are wondering whether they have made a mistake.
