Hubbard comes from a relatively privileged background and competed in men's weightlifting with mediocre success before swapping to compete against women.
Let's not forget the women who have been pushed down the rankings. Kuinini 'Nini' Manumua of Tonga would have been in Hubbard's place.
Nini has now also been allowed to compete in the Olympics, under a special scheme to give under-represented countries more of a chance. Without Hubbard, another woman from a developing country could have had that opportunity.
If Hubbard comes in the top three, as is likely, another woman will have been cheated of an Olympic medal.
The injustice ripples all the way down the rankings, and its influence is likely to spread across other sports. That will be Laurel Hubbard's biggest effect on international sports.
