I highly doubt this is what is happening. As you all know, Taylor Greenfield is not the average girls basketball player. At 6'3 with the ability to play on the perimeter she is a top 25 recruit nationally. If accepted, she'll be offered. She has been recruited by Stanford for some time now and she did visit Stanford back in November.
The Stanford application process is quite complicated. They normally don't get their first commitment until September of the recruit's SENIOR year. The coaching staff in Palo Alto will target a wide range of recruits, then once there is mutual interest Stanford will ask for the recruit's transcript with all their GPA's from the various semesters as well as if the recruit has been taking an AP honor classes, among others. Then if the admission staff okay's the transcript, the coaches can send these recruits an application to apply to the school. The applications consist of letter's of recommendations from teachers, transcript of all your grade's from both your sophomore and junior years of high school, your SAT and/or ACT test scores in detail, as well as the numerous essays the application consists of. Then once the application is mailed back to the university, the admission staff reviews and discusses it and then the final decision is made, whether or not the recruit is accepted, then the coaches are told of the verdict and the recruit's are notified. If the recruit is accepted, they then can be offered a full-ride guaranteed scholarship.
As you can see this is a very complex process. This is why there are very few kids who apply to Stanford and go through this whole process, get accepted, get offered ... and then decide to go elsewhere. Some that come to mind include Notre Dame's Skylar Diggins. She went through the application process, was accepted, offered, and even came all the way out west and officially visited in October of her senior year. She then chose the home town Fighting Irish over Stanford. Sue Bird was another recruit who applied and was accepted, she then chose UConn over Stanford and Vanderbilt. Christina Wirth chose Vanderbilt over Stanford, despite being accepted by the school. So there are some who do turn the Cardinal down but 85% of the time, when the recruit applies and is accepted, they end up on the Farm. Shoni Schimmel, the No. 8 recruit in the 2010 class flat out said Stanford is her dream school though she didn't have the grades, so don't think that any athlete who expresses interest gets in.
The Cardinal have 6 available scholarship to give in this class. They already have two recruits who have committed for the 2010 class:
No. 18 Bonnie Samuelson, 6'3 Small Forward (Huntington Beach, Calif.)
No. 35 Amber Orrange, 5'7 Point Guard (Houston, Texas)
