I definitely think this is playing a bigger part than most like to admit or understand. Though Olympic athletes train hard all the time my understanding is training leading up to an Olympic year can be a whole other beast, physically and mentally. These athletes were prepared to compete in 2020. Then COVID happened and the Games got postponed, which essentially added another year of training for the Olympics. It had to have taken its toll, more on some, I’m sure, than others. The IOC probably should’ve just scrapped these Games, but we know money is at the root of the decision to push on.
