I've always enjoyed myself, you're right, it's just like supporting your team. If you find yourself obsessing over the minutiae over on PFF.  Then you should take a step back for sure.

Played for many years, prefer to just watch my favorite team instead.

It would be a waste of time if that became the center of your life; as long as it isn't, it's like following your favorite team's season, I don't see anything wrong with it, on the contrary, you enjoy it a lot.
