Not sure what you're complaining about Quicksilver?

Last I checked, there are 4 (FOUR!) channels of Olympic coverage: NBC HD, UHD, MSNBC, and sometimes even CNBC. When I get tired of swimming, I just flip over to another channel to watch boxing or fencing. I think NBC has achieved good balance wih both live and taped events, considering the 12-hour time difference.
If you consider the sheer volume of events (30+ sports) it's impossible to cover every single match in every single sport, but I think they've captured a pretty big cross-section so far.

My one main complaint is the relentless onslaught of commercials, but that's been the case for every Olympics.
