Well i can summarize it with one word only DOMINATION, 46 golds, 121 total, unreal
Swimming+Athletics+gymnastics produce most of the medals, however also some surprises , like sailing medal, like Thrasher with the first gold.
Brady Ellison finally won a medal with a much better performance then London.
Hard to talk about disappointments after winning so many medals but i do have to mention women's soccer, jordan burroughs in wrestling, gibb/patterson in beach volleyball, women's volleyball, though winning a medal, could've won gold and missed a huge opportunity, and off course the 400 gold that was taken from Felix on the line.
Yet so many breakout stars to the world that surprised a lot of people, Ryan Murphy, Lilly King, Simone Manuel, Ryan Crouser, Clayton Murphy, Matt Centrowitz, and off course Simone Biles, who is amazing for 3 years already but first appearance on an Olympic stage.
There's a lot more to stay, so probably later on i can write a more detailed sport by sport recap for USA
