Our entire family is excited about the Olympics! My biggest concern is NBC; they're an awful network in general, but they absolutely butcher sports programming. And Bob Costas may be the only person on the planet as annoying as Alex Trebek.
As for the sports, where to start? Soccer, volleyball, swimming/diving, track & field, and so on.
But what really makes the Olympics are the lesser known sports that we only focus on every four years, like curling in the winter games. In the summer, it's water polo, equestrian, team handball, ping pong, and rowing/kayaking.
The sports I can less about are boxing/wrestling and basketball
