I don't understand the disparity in start times for early games vs. late games for American sports.  Early games start at 12-1 pm on the east coast, which is 9-10 am on the west coast.  Those are reasonable times for reasonable people on both coasts.  Unless you work the night shift or are weird in some other way, you'll have no problem watching those games in their entirety. 

Late games, on the other hand, start at 7-8 pm on the west coast, which is 10-11 pm on the east coast.  No normal person on the east coast regularly stays up until 12-1 am to finish watching these games.  Games that start this late pretty much only happen on the west coast, and because of the relative time frame, I'm led to believe the target audience is solely on the west coast.  Which is odd, both because I'm an east coast native, but also because 80% of the population lives on the east coast. 

Finally, we as a country need to address the start time of prime time games.  These games start at 8-9 pm on the east coast and last until 11 pm or 12 am.  On the west coast, this is 5-6 pm until 8-9 pm -- easy peasy.  For people on the east coast, this is too damn late.  This isn't a big deal for a standard Monday Night Football game or whatever, but it's significant for games like the Super Bowl or College Football National Championship where a sizable portion of the population (again mostly on the east coast) are watching.  I would like to formally propose a constitutional amendment to start prime time games at 7 pm ET.  People on the west coast can accommodate a 4 pm start time; it's for the good of the country. #sports
