To answer your question, knowing that Stanford University regularly wins the tiltle as the best all-around sports program in the country, and after doing a little research, how about this:
1996-97 Mens Cross Country,
AND Womens Cross Country finishing their seasons #1 in the country. And oh, by the way, Mens Volleyball finished #1 that season, too.
