I don't watch "football", but I consider myself I big sports fan. I myself play Basketball, so I find it entertaining and impressive to watch since I understand it better. I also like american football, even though I've never played it.
as to why I get worked up about it, is because it's simple competition. I love to trash talk other fans, as well as defend my team from trash talk from other fans.

Lakers fans will never know what real winning feels like.
I Basically live in Dallas, Texas, and I'm a huge fan of the Lakers. as a result, I am surrounded by fans of the Dallas basketball team, while I cheer for the rival Lakers. I find it fun to be able to trash-talk everyone around me, and it gives us something to discuss. I do find most fans to be completely idiot in their trash-talk, which can be annoying to deal with.
overall, all fans can discuss sports because it's something we all have in common. I can hardly discuss Code Geass or Naruto theories with anyone, but I can get in a Basketball argument with most of the people of Dallas
