Pro sports and college sports have pretty much been corrupted by greed and all the other things that make a lot of the pop culture trite. It's getting to the point where only pee wee ball will be worth watching.
That said, I don't think it's an addiction and I don't much care that others like it. It's a market thing. If people are willing to pay hundreds of dollars to see pro sports, they should be allowed to do so. No big.
Competition, team play, etc., are all good things for mind and soul. Pro sports and for the most part, college sports in this country, aren't that. Too much sleaze for the likes of me. But as long as it doesn't interfere with my life, I don't much care. As long as it doesn't hurt anyone, do whatever makes you happy.
