No, I'm not even an alum, and my main contribution to Duke has been tuition money for my kids (and just enough extra to get invited to the pre-commencement breakfast for parents' fund contributors so we could get a good parking space
) So I'm definitely not part of the 0.1%. And while your math sounded a bit extreme to me, I haven't done any math of my own, so my challenge is really just a guess.
I agree athletic success can have a big impact on a university--I teach at George Mason, which experienced a big increase in applications for a couple of years after the Final Four trip in 2006--especially applications from outside Virginia, where many people were just hearing about the university's existence for the first time.
And clearly top quality sports, especially basketball, are a very significant part of the Duke brand, a brand that is obviously enhanced by talented and personable basketball players like Tyus, Jahlil, and
Justice winning a national championship, not to mention talking openly and frequently about how much they love Duke. Didn't mean to undervalue their contributions, just thought we might be undervaluing other people's.
