I think Alyssa's biggest issue is in her head. Even when she won silver and then gold at the 2 grand prix events several years ago, she said it was because she didn't have a lot of time to over think. By reports, she skates great during practices. My guess is that she has improved her technique overall, but the competition nerves prevent her from fully executing those improvements.
My impression of the article is that Alyssa hasn't decided if she's going to continue competing and, if she does, who will be her new coach. Both Brian B and Yuka were mentioned as her mentors during Nationals.
Does Linda Leaver still coach? It seems like her only hugely successful skater has been Brian and that was years ago.
I wonder if Brian Orser is an option. If I recall correctly, he had competition nerve issues for a while and he might be able to help her having gone through it himself. Since Alyssa has graduated from Bowling Green, she could consider relocating.
If she wants to stay in Detroit, working with Yuka and Jason is a definite option.
