If you know anything at all about basketball, you should know by watching the game that these two play good team ball and also are the best of friends.

If you don't know anything about basketball please choose a subject you can discuss intelligently.

You are saying that you can tell they are best friends by watching them play ball and if we can't see that, then we know nothing about basketball. You like to talk about other teams players, but you don't want anybody to talk about yours, and if they do, they know nothing about basketball. So if you make cracks about other teams, then you know nothing about basketball. OK
