I don't know any polo players that aren't surf rats too, most also are on the swim team.
Water polo is kind of the elitist sport in CA, maybe like Lacrosse is in eastern prep schools. It is a very small community, everyone knows everyone and it is very generational. People who played at USC 60 years ago are still involved and are seeing their great grand kids in the sport.
Since polo is biggest at the elite universities in CA, Cal, Stanford, USC, Pepperdine, UCLA, UCI, UCSD, Harvey Mudd, Pomona-Pitzer, etc high school polo players know they need good grades to get to the next level.
Most of the top water polo high schools in southern California like Corona del Mar, Harvard Westlake, Loyola, Newport Harbor, Long Beach Wilson, Laguna Beach, Malibu, Coronado, the Bishop's School, La Jolla High, Carlsbad and so on are from wealthy areas. The hard work and discipline it takes to be great at this sport blows the image of the idol rich out of the water. The guys are tough, dedicated and disciplined. You have to be when your first practice of the day starts at 5:45AM.
It would be cool to have Will as the narrator of the next CAP story (or one of them) and have Will playing polo.
