Even if Dressel goes on to do some truly remarkable things, he'll always remember the world championships along the Danube. He won the 50 and 100 freestyles, and nearly took down Phelps' world record in the 100 butterfly. Phelps' feat still stands supreme since five of his seven golds were in individual events, and he didn't have the benefit of the mixed relays. Dressel surged to the front with a down-and-back time of 49.76 — the only butterfly swimmer to break 50 seconds. As everyone else walked off deck, Dressel lingered a bit, watching a replay of the race on the video board.
