If you can't make it to the stadium and really can't watch it on your TV, and you don't have access to an "official" stream, then there's always http://ifirstrowus.eu/sport/american-football.html for live streams. They usually have at least 1 and most often more streams available, but the quality can be erratic sometimes.
A word of warning, kman has provided a site to use that is totally bogus. I tried accessing and I'm currently fighting numerous $39.99 charges to my debit card fraudulently.
I'm sure your bank would be very interested that you are fraudulently fighting several $39.99 charges to your debit card.
What were they for? California psychics? online gambling debts? your online fetish porn habit?
