I suspect that most kids don't want to be told about their future away from professional sports. It might be useful in recruiting kids who aren't very good. But "blue-chip" recruits are likely to be more interested in their chances of making it to the next level - not the value of a degree from Duke.
That's not to say that, realistically, this is a credible point about one of the virtues of actually coming to Duke. But in terms of getting the most talented kids to come here, I don't know that it's the best sales pitch. It's pretty much in one ear and out the other.
