It is funny, I lost all interest in the NFL in the early '80s when I moved to Washington. That year the players and owners were throwing their usual tantrums. I started watching PAC 10 football and haven't watched a complete NFL game since then.
That said, for a few years recently I had HBO and watched Hard Knocks. I enjoyed the show. It didn't peak my interest at all in watching any games but I still liked the show.
