I'll copy/paste what I said in another thread/forum in response to there being a petition to change the rules to 3 per country for the AA.
Would there be a petition had the Russians gone 2-3-4 and Grishina, lets say, missed the AA?
There are rules (what we think of them is a different matter) and criteria. Every sport has them, especially at the Olympics. Every sport NEEDS them. In athletics and swimming, there are ridiculously good athletes left off whole teams because of a minimal number athletes from each nation. Unfortunately today Jordyn wasn't good enough to meet the criteria - that being to finish top two in your nation.
I also wish it was 3 per nation for the AA, but how long would it be before people thought it should be 4? I seem to remember that back in the days of 3 per country, there were those who thought there should be no limit to the number of gymnasts from one nation in the AA at all. Where would it end? I'm sure Kyla Ross, who has an Amanar for goodness sake, would have placed very highly in the AA as well; she didn't even get the opportunity to make it.
I feel for Jordyn, because to be that highly favoured to win a gold and to then not even make it to the final must be tough, but she had to earn it today, and she fell so marginally short. She wasn't entitled to automatically be in the AA (not that I'm saying anyone here is saying she was)
I have a feeling she'll nail it on Tuesday. I hope she does, and I don't even like her gymnastics that much. Seeing her literally sobbing in the media zone was a sad sight.
Basically, you have to draw the line/limit/standard somewhere. Whatever that line is, it'll piss someone off.
