The IAAF's "three athletes per country rule" often leaves out deserving athletes a chance to compete for a world title. Sometimes the fourth, fifth, sixth, or even seventh ranked athletes in one country are good enough to be top ten in the world. Without this rule, the World Championships -- which start Friday in London -- would look a lot different.

The NCAA doesn't stop any school from qualifying more than three athletes in an event, so why doesn't the IAAF do the same?

Here's what Team USA would look like if the IAAF based their world championship fields on top-24 descending order lists.

Note: When generating the world top-24 descending order lists, I did not account for athletes who have chosen not to compete in a certain event. This list is purely based on if that athlete hit a mark within the IAAF world standard qualifying period. So for example, Ashton Eaton is on this list. This list is for entertainment purposes only.
