Like any athlete, if he gets chosen to go, I can't imagine he would "decline". Noone should ask that of him. It's his dream to compete at the Olympics. Just as it is Takahiko's. So whoever gets chosen, I sincerely hope they won't get bombarded by people discussing that "it should have been the other one" and telling him "you should give your spot away".
--WHAT I HOPE WILL HAPPEN
They send Kozuka. They all competed for 3 spots with a huge amount of pressure, and he earned his 3rd place today.
--WHAT I THINK WOULD BE FAIR
They organize a shootout between Kozuka and Takahashi at a later date: 4CC or just the 2 of them, factoring in their performances of the entire practice sessions to figure out who's fitter.
--WHAT I FEAR WILL HAPPEN
They send Takahashi, basta.
--MY PSYCHADELIC NIGHTMARE OF WHAT HAPPENS
They announce that they will only send 2 men to the Olympics and give away the last spot, with the message that "WE DO WHATEVER WE WANT! THIS IS NOT A DEMOCRACY!" Of course, this results in the JFSF being overthrown in a bloodbath. The Japanese Government gets overthrown as well, kind of as a casualty. Vive la révolution!
