One team that did not make the super-regionals, but is worthy of notice, is the University of Washington. As noted in this article looking forward to next year's Pac 10 season, star pitcher Danielle Lawrie is expected to return to the Huskies after pitching this year for the Canadian Olympic team.
UPDATE: As is inevitable, I tend to omit a few players whom many observers feel are important to their respective teams, either as departing seniors or returing players. Both to publicize the list and to allow others to suggest additions to it, I traditionally start a discussion thread at Ultimate College Softball. Here is the current thread, which contains several suggestions for additional players. My thanks to the contributors to this discussion from UCS.
