Ok, I'm just having a look at the thread which this discussion is on the other board, which raises some interesting points.
Of course, if you enjoy watching the sport and watch it often, then you are a fan.
Watching a lot of tennis, listening to the commentaries and reading about it helps more with understanding the sport, or at least what is relevant in able to enjoy it, than playing it unless if you play at a very high level so you can still be fairly knowledgeable if you do that.
Playing is a really good way of learning the degree of difficulty of each shot amongst other things in comparison with other shots, etc so I think people that play can appreciate it more, but of course that doesn't make us any bigger fans than those that don't.
