There's a code to that Grecian urn, the amphora SI awards to its Sportsman and/or Sportswoman of the Year. Study the covers laid out on these pages and you'll see the spirit of the times reflected in our choices. Doctor-to-be Bannister, sprinter and devout Christian Morrow, and scholar-quarterback Baker are felicitous representatives of the gray-flannel-suit 1950s and pre-Dealey Plaza '60s.

Solo performers Rose, Evert, Cauthen, Nicklaus, Leonard and Decker marked the decade beginning in the mid-'70s. And as the population grayed, who better to honor than superannuated achievers like Moses and Abdul-Jabbar, and whiskered coaches like Paterno and Shula, and the singular Arthur Ashe, who made a difference in retirement and now, still, in death?
