I realized that I never actually responded to this...
Oh boy, don't even get me started!!! I absolutely LOVE Olympic coverage. I will record as much as my heart desires, and as much as my DVR can handle.
While I enjoy the primetime coverage, which pretty much encompasses those events in which we are dominant, it's actually the other stuff (i.e. whatever is broadcasted during the day) that actually excites me the most. It's the events that we don't really know a whole lot about because it's pretty much popular anywhere and everywhere outside of our borders.
As for specific events: Swimming, Diving, Track and Field, Badminton, Handball, Indoor Volleyball (Women's, not so much men's), Beach Volleyball, Rowing, Water Polo, Hockey (yes, even field).
This year, I might catch some Rugby and Soccer matches, but not sure if they will be as often as any of the events I've mentioned above.
