I think the larger component is breadth of offerings.  Especially in women's sports.

Stanford and UCLA have done well in women's sports, but U*S*C was late to the party and has been playing catch-up.

NCAA women's team championships

46  Stanford
39  UCLA
29  North Carolina
25  LSU
23  Texas
21  Maryland
19  Georgia
17  Florida
16  U*S*C
14  Connecticut

In men's sports, UCLA, Stanford and U*S*C still are the top three, as they are on the overall list, but in a different order.

NCAA men's team championships

84  U*S*C
74  UCLA
62  Stanford
51  Oklahoma St.
42  Arkansas
34  Michigan
27  C.al
26  Yale
24  Iowa
24  Indiana

Breadth of offerings is a factor, but it's not a complete answer. The schools offering the largest numbers of NCAA varsity sports, besides Stanford (30 NCAA sports), include Ohio State (32), Penn State (30), Michigan (29), C.al (27) and North Carolina (27). (There may be others in this range -- I didn't check all of them.) Those schools are well behind Stanford on the list of total championships. Offering a lot of sports is not enough to put these schools at the top of the list.
