I think it's a good move for Bradie. Tom Z got Mirai her 3A, and Bradie needs to up her technical game.
As much as people are worried about her overall skating declining (which is possible), she needs more firepower to compete with the Russians/Kihira/Liu. If she wants any hope of a medal in 2022, getting a 3A/quad is a must.
I agree, provided her ultimate goal is to become more relevant internationally. The jumps have to be upgraded, that's all there is to it. I admire her for not throwing in the towel. If she goes down, she'll go down swinging.
As far as artistic skating goes, I did see some improvement in the most recent season, and I hope that will also continue. We'll see.
