If I have to add my few sats though, might be better to add "Summer" to the title to distinguished it from the "Winter" Olympic games.
As for basketball as this is the sports that I followed, the USA will send their best team again, could be another Redeem team to get back their old glory in Basketball. So stars like Lebron James and Steph Curry. Not only that but the coaching staff as well will be lead by Steve Kerr, Tyronn Lue (L.A. Clippers) and Erik Spoelstra (Miami Heat).
Also might be good to see who will dominate the track and field specially the 100 meters with both US men and women and then their rivalry with the Jamaicans again.
Well, the "Winter" Olympics is not in another 2 years from now. It shouldn't be too hard to distinguish which one is happening right now, looking at the sports that are being played during the games. Usually, the Olympics means the Summer Olympics, and when there's the Winter Olympics, it is denoted as the "Winter Olympics". Some facts on how the Winter Olympics are below:
Initially was "Nordic Games" organised by General Viktor Gustaf Balck in Stockholm, Sweden, in 1901 and were held again in 1903 and 1905 and then every fourth year thereafter until 1926. Balck was a close friend of the Olympic Games founder and he attempted to have a few Nordic Games into the Olympics. The idea was rejected initially but later was turned into the Winter Olympics and was first conducted in 1924, which was held in Chamonix, France.
