According to ESPNW:

Who are the best women's college basketball players in the country?

We'll leave categories to the Academy Awards. We're not worried about point guards or centers, small forwards or big guards. All we care about is that you are better at what you do than someone else is at what she does. Score points, set up points or prevent points. Better yet, do all of those things. Just be excellent wherever you play on the court and whatever your skills.

After tallying the votes from Charlie Creme, Graham Hays and Mechelle Voepel, espnW ranked the best players in the nation.
A complete description of each of the Top 25 players can be found at the following link:
