Day 4: Swimming, Gymnastics, Basketball

Katie Ledecky is on her way to legend thus far. As for Michael Phelps, I think it's a bit too egotistical, but you can't deny his dominance. I wouldn't be surprised if he seriously considered the 2020 Games. As improbable as that seems, I didn't think he'd still be dominating here and yet he is.

No second upset for Croatia as they lost to Argentina in basketball, but I still hope they make it to the tournament round.
