What can possibly be learned from these athletes' dying young, anyway? We barely got to know them. As the new year opens, it will become harder and harder to remember their names and their yet unperfected skills. They drift away from us, so many of them unanchored by the weight of achievement, and take up their haunts in a dim ether. Yet the collective loss of 1993 remains troubling. All this youth just scrapped. Did we have so much to spare? Was it so easy to come by? We wonder: Should we have taken better care of it?
