It is not exactly a tough sell to recruit Olympic athletes to Stanford. 
- You are going to Palo Alto, one of the morr expensive neighbourhoods with average home price of $3.3M, for 4 years.
- beautiful CA weather for 4 years.
- You are getting a scholarship from one of the top 3 universities in the USA.
it's not exactly that hard to recruit top athletes here, which is why Stanford wins the Director cup every year.  Over 20% of Olympic athletes came from CA for the USA.  Stanford, and in some ways Cal as well, have these built-in advantages few schools have.
