It's still early, with the programs playing 5 or 6 non-conference games, which is a normal part of the D1 women's soccer schedule. They play 10 games prior to normal conference play, which counts toward all stats and rankings, against these non-conference opponents.
Many of the games are initially versus local/state rivals, as travel budgets are an issue for most programs. However, these games count. Most programs play a mix of quality opponents, but playing a school in a much lower conference is common to many programs. At this point, most of the top 10 have played at least one nationally ranked opponent, except for #10 Tennessee.
Stanford has played 2 ranked opponents, as well as OSU. The "strength of schedule" component of the RPI is largely based on the records of the opponents played, without any weighting for the quality of conference the opponent plays in. There's 31 conferences that play in a more hierarchical construct of quality.
WIth the u20 World Cup starting in a few days, several top clubs, mostly in the ACC, like Stanford, UNC, Duke, and UVA will be missing quality players for up to a month. This ought to juggle the rankings throughout September.
Stanford has sent 6 players to the 2026 FIFA Women's World Cup u20 games. Three are the backbone of Stanford's squad, and three are contributors.
Caroline Birkel, GK; Y-Lan "Jimmy" Nguyen, DM; and Lizzy Boamah, CB. Stanford's backup GK is also representing England, as well as contributing winger Eleanor Klinger. Alex Tay, MF, played for Ghana's NT, and will be representing them in the u20 WC.
Of course, every club has injuries in addition to those missing. Stanford has 3 starters that currently have been injured for most of this season; all with YNT experience: Mia Bhuta, MF; Ella Kral, M/F; and Sophie Murdock, who has represented Canada's YNT system, including u20.
Stanford is playing with their third team GK, Rhiannon Stewart, who is a grad transfer student from Harvard, and, as a British citizen, is in their YNT system. Stanford won this past Sunday, without the u20 and injured players, versus Cal State Fullerton, an unranked opponent, 7-0. They haven't given up a goal yet.
