blah2008, with scholarships such as Rhodes or Truman or Churchill, I think looking at the entire history is more telling given how few are given out each year. Besides, why penalize an institution with a rich tradition for having had a few dry years?
That being said, Columbia has graduated roughly 17,000 undergraduate students since 2000. Michigan has graduated 55,000 in the same period. To be honest, I am not sure how 2, 8 or 12 students winning awards in that span of time can be considered a telling statistic. That is why I really consider the Fulbright a better metric. At least there is critical mass required to pass judgement.
