Caeleb Dressel’s freestyle and butterfly are killer. He won the 50 and 100 yard freestyles at NCAA, and also upset Olympic champion Joe Schooling in the 100 yard butterfly.

While Dressel’s above-water speed is no joke — he swam a 21.53 at nationals in 2015 long course — his underwaters have become somewhat legendary.

Take the Rio Olympics, for example.

He led off the 400-meter freestyle relay for the American men, and when you watch the video of his start you understand why.
