Just not my thing. I do catch a few highlights on the news and stuff. I could never carry a conversation about any sport or the people that play it. At least not for long.
When it comes to the "pick em" stuff, I wing it, without ever watching a game all season.
I have even worked in sales for a pro hockey team...games were mandatory. A friend of mine directs a very popular univeristy arena....I have never even asked for free tickets!
