Katie Ledecky did not win a gold medal.
No, the sky is not falling – Ledecky still captured silver in the women's 400 freestyle – and she has the 200, 800 and 1,500 freestyle events remaining in these Tokyo Olympics, as well as the U.S. women’s 4x200-meter relay. And, frankly, her runner-up finish in the 400 free to Australia's Ariarne Titmus by .67 of a second wasn't even terribly surprising based on recent history.
She was still responsible for one of the two medals Team USA captured in the pool during Monday's early action, the other being a gold secured by the men's 4x100-meter relay team led by Caeleb Dressel.
