Hardcore Olympics fans may already know this, but more casual followers may find this fact interesting:
The USA swim team is so dominant/deep that they regularly have their B team swim the preliminaries so that their best swimmers can rest for the finals and their individual events.
What many people don't know is that swimmers who only compete in the preliminaries (and get swapped out for the finals) also get the medal...not just the people who swam the finals. So even though you see 4 guys or girls on the podium, up to 4 other people also got medals.
Therefore, winning a single relay event means that up to 8 American swimmers get a gold medal.
This is especially true for the medley relay (4 people, each who do a different stroke): USA always sends their #2s (for each stroke) to do the prelims, and then have their #1s (completely different people) do the finals. So for example, both #1 and #2 American breaststroke swimmers can get a gold medal in the same event.
For the freestyle relay, this means you can just be the 6th or 7th fastest American freestyle swimmer and still get to go to the Olympics and get a gold medal. That's exactly what happened this year with prelim-only swimmers Jimmy Feigen, Blake Pieroni, Clark Smith, and Gunnar Bentz.
At the 2016 Rio Olympics, USA won gold in 5 out of 6 swimming relay events (and silver in one).
So in just these 5 events this year, 33 Americans got gold medals even though only 17 people swam in the finals. Doing this basically doubled the number of Americans who went home with a gold medal.
