Drew Bowers is a student at Duke who has put together a pretty cool app called Draftpedia. It tracks NBA and NFL draft data, rosters, and statistics from the last 40+ years. It lets you sort the data in a lot of different ways - one way is by college so you can see and track every pro that attended Duke (or any other school) in a single list. It should be a great reference tool for sports history and random trivia.
We downloaded it and found it well organized and useful. And it's free, which is hard to beat.
Here's a review from the Wall Street Journal as well.
