Upperclassmen required briefs? Swim team?

[sebbie]

I'm convinced that this is more about going to interschool swim meets and merely observing what the best swimmers from the other schools are wearing when they clock their best times. By the following meet, the younger and slower swimmers and even some of the swimmers on the weaker teams will be wearing whatever it was that the best swimmers were wearing at the previous meet. It's really the rivalry that determines the choice. And if the best swimmers look particularly intimidating in their snug-fitting briefs, the other guys will soon be doing the same. Of course, if the best swimmers are all wearing jammers,...but the trend has been away from jammers and back to briefs.
