It’s the middle of football season in America and for fans of the sport it can be difficult figuring out how to catch games in Japan. Here is a site that offers multiple links to nearly every game. In my experience, the links work well and the video plays in reasonable quality; it’s not HD, but it does the job. There is one catch in that the games are shown only live, which makes them difficult to watch given the time difference. But if your team has a 4:30 game (EST) on Sunday, then you can catch most of the second half before going to work on Monday morning.
If someone knows a better site for watching American football games, please leave the link in the comments section.
