I believe that Anita will have medal, even gold, she is very experienced athlete that changing the coach shouldn't too much affect on her, it could be issue if the Games would be held in 2020, not a year later. She training now very hard in Qatar and I'm confident that she will return to her place where she belong.
I will not predict anything now, after season which was badly affected by covid like everything else. Maybe in May/June I will decide to make any predictions.
We also must remember that if some big favourite athlete will be infected then might not be able to compete in Japan. But let's see what IOC will decide in near future. Also tomorrow Japanese PM will decide if they will introducte state of emergency again by third wave of covid with this new strain of virus.
