Problem with Momota is he doesn't seems to be giving his best. Whether it is Physically or mentally that is preventing him from giving his best, I don't know. Or a little bit of both. When we give our best and lost, we experience frustration. Fears of having to experience frustration can be a big problem. So to avoid frustration, we consciously or sub consciously tell ourselves to not give our best. In that way when we lose, we have excuse and tell ourselves we didn't give our best for this time. This is an unhealthy pattern even though temporarily we feel consoled because our lost is expected. But in the last tournament against china WHY, I felt he did well even though didn't win. He must not be afraid to lose while giving his best with determination to win. Another thing is it could be physical. Before the accident he is not overly occupied with a little pain here and there after a tough fight. Now, every little pain becomes a cause for worry whether something from the accident is surfacing. If in that accident, no one died things might be different. But someone died and he was sitting just behind the driver as I understand. This means he realized he came this close to suffering the same fate as the driver in front of him. It is a shock he must recover from. Eyes movements are important for a fast game like badminton. Of all things, he had injury in the eyes. The eyes might become lazy a bit and choose to relax more taking it easy in such a case. Finally, he alone must choose. Whether to let the unfortunate incident end his badminton passion or work to overcome all negatives impact ... If he chooses to overcome I think it's better to start from basic. This is because he had a very complex skills that has layers built upon layers in order to cope with different opponents. He can afford that before the accident. Now, it will be a mistake if he tries to rely only on just energy conservation layer or excellent racket skill layer. Those layers used to stand very firmly on very good footwork and alert eye movements. If anything was not working, he could quickly activate the basics. Now, the more advanced layers stands on shaky foundations.
