From a story on axios.com by Jeff Tracy headlined “The greatest American multisport stars”:

In the wake of Jim Brown’s death last week — and Dick Groat’s last month — we were debating the greatest multisport athletes in American history. Here’s our top 15.

1. Jim Thorpe (1887-1953): Olympic gold in the pentathlon and decathlon, college and pro football Hall of Famer, six years in Major League Baseball and barnstormed as a pro basketball player.

2. Bo Jackson (1962-present): The athletic freak won the 1985 Heisman Trophy, spent four years in the National Football League (18 TD) and eight in MLB (141 HR).
