Which is a fine argument. But as far as predicting possible Worlds results, it is also a perfectly logical argument to point out that Young has the firepower to control her own destiny and outscore Bradie. (Not to mention that Bradie's SB is from a home event, which Young did not have). And, in fact, Young defeated her in head-to-head competition on the GP. (A well skated competition for both young ladies, really. Not perfect for either, but quite good skates for both athletes when one compares these performances with the quality of their performances over the past couple years). They are close enough that it could go either way.
Bradie has more senior international experience, which can come in very handy at Worlds where the stakes are very high. Young has more difficulty and while I do have questions about her ability to skate her best under pressure in high-stakes international competition, she has stood up quite well under pressure at Korean Nationals more than once, an event which often requires an absolutely clean skate to win. I simply do not see a good reason to underestimate her. Both young women are in the game. (Providing they make it out of their respective Nationals).
