In any logical universe why would you take away over half a teams schedule when discussing how hard it is? The conference certainly impacts how coaches schedule and how they gear up for league play. Since 2015, Tara has played at Gonzaga, Texas, George Washington (Jonquel Jones), Tennessee, Ohio State, Baylor, an explosive Buffalo with Cierra Dillard on their home floor.
Tara has consciously made an effort to aid the rise of the Pac-12 as a conference in encouraging her peers to schedule tougher contests, which has led to what is now considered THE toughest conference in the country with the logjam of excellent teams. As
@willtalk pointed out, travel is also a huge factor for Stanford. Stanford has historically played a maximum of 3 games on the East Coast during the season. This makes it tough to have frequent games against the best programs since they can't do a home and home easily given the limitations of the travel they have AND trying to schedule homecoming games where possible for their team. For example, Buffalo was a homecoming game for the Canadians on Stanford's roster at the time, and George Washington was Marta Sniezek's homecoming game.
If you want to continue to sneer down your nose at a program that has consistently scheduled well just because it's not UConn-esque, fine. It's just ridiculous that you're belittling Stanford's schedule when it's typically a top 20 non-conference schedule every year. If we were talking about Maryland or Duke then we can have a field day.
