Not entirely an accurate comparison. And still too early to tell. Bartsch was also ~25 when she started "making waves" and Adams is what, 29?
I agree that comparation between Bartsch and Adams is not nearly real and ideal, but because of some other reasons, if we talk about age actually Bartsch make a big step and begin to play for USA NT with 27 years, so in that way this 2 are pretty similar.
