We know nothing really, all we do is speculate. However to me, I think replacing Keegan didn't work for him. I don't think he was ready to skate in the team event. Then suddenly he needs to, then suddenly he's skating early, then he messes up and the team might not qualify because of him. Tries to redeem himself for the free and bombs even more. By the time the main event arrived he was fried. Then he draws first again. Personally it looked like someone who cracked under pressure and whose plan was derailed and it spiralled out of control. Total conjecture of course. Some of these skaters visualise every moment for months and months before, when the micro managed plan is changed totally, the ones that aren't as mentally strong can't always handle it.
