I don't want to make predictions, but I think that Agnes Zawadzki and the Shibutani's will win medals at NHK if they skate well. I'm really excited to see Agnes skate this year, she has a great personality, impressive jumps, height (she's a welcome 5'6"), and when she's confident, a wonderful presence on the ice. The Shibutani's skate with energy, excitement, and wonderful flow. Best of luck to all of them.
I'm very interested to see how Mao fairs. I admire her commitment and desire, although I wonder if she is too fixed (in the worst case "obsessed") on winning a OGM that she is missing a lot of life along the way. Obsession is a detrimental mental state, it will lead to failure not success. So I hope that Mao has a healthy desire to just skate her best, be a happy skater, and enjoy her competitions. When she skates with freedom she is a lovely vision on the ice and one of the most talented skaters in the world today. Two solid performances at NHK will land her in 1st place without a doubt, and be a treat for all of us skating fans.
