Dan, do you really know Chuck?
RefTn, you age has NOTHING to do with anything! Your experience does. I think Jurrasic is trying to tell you that you should experience some of the things you talk about. Saying what someone told you without experiencing it is a no no.
Also, every illegal screen doesn't have to result in the offensive player catching the ball. If you use absolutes on plays like this you WILL get surprised.
Chuck, are you saying that you would't call an obvious screen that everyone can see if it happens at the end of a game? I think it would depend on what kind and where this illegal action takes place. I wouldn't say I absolutely wouldn't call this. I understand what you are saying though.
