The dude who wanted names of people from prep schools who went pro...you are obviously not very educated in this matter, because there are tons. Check out hockey:
Tony Amonte, Brian Leetch, Rick Dipietro, Doug Brown, Scott Young, Mike Dunham, Chris and Peter Ferraro, Eric Lecroix, Marty Mcinnis, Mike Mottau, Tom Poti, Jeremy Roenick, just to name a few.
Want others? There are tons of pro lacrosse players, but I doubt many people have heard of them.
Fair amount of basketball players, but I don't follow bball well enough to give you names off my head. Prep schools don't tend to be very good at football, so I doubt there are many there. A ton of olympians are prep scohoolers, especially sports like Crew, which are huge there.
YOU LOVE IT
