I used to be hugely into it mid 90's/early 00's. Back when Don Lane used to do 3 hours of highlights and one key game on Tuesday nights at 11pm or something.
I usually try and watch one game a year, usually the Superbowl, but the one American friend I have down here is moving house today... plus after last year's thrashing of his Broncos, he isn't so keen to watch the Seahawks defend the title.
