Ashley is really tall for a pairs girl. She and Tim took a long time to hone those elements and be completely at ease with each other. Okay their lifts are not top-class but they have made such progress over the last few years. This year they look more secure than they've ever been.
Americans are often too quick to embrace a new thing and discard something good.
Ashley and Tim had a rough season this year. So has every U.S. champion pair since 2014. It's a lot of pressure to be the gold medalist being chased. No pair has repeated as US champions in consecutive years since 2014; that includes Alexa and Chris. Ashley and Tim have accomplished so much, and this is still only their 4th season together. They have a strong connection and a mutual vision for their skating. I could be wrong, but I can't imagine Tim breaking with Ashley unless she volunteered it, and I think she's too fierce and passionate about pairs skating to do so.
So many people, and Alexa herself, are thinking in terms of 2022. But she's got more time than that, if she really wants to fulfill her potential. Look at Aljona, look at Zoe Jones.
