Help me not be a clueless commentator.

Thanks for the responses. I especially appreciate the training tape. Is there a similar one for women's games? A couple follow up questions.

The restricted arc only applies to a secondary defender right? A primary defender can still draw a charge in the arc, correct? If a secondary defender is in (or above) the arc and there is contact, is it automatically a foul?

When y'all say commentators get "rules" wrong, specifically which rules would you say are the commonly misunderstood? I'm not expecting to be a rules expert, but maybe 3-5 of the most common misconceptions by fans/commentators?

I've downloaded both rule books. After my football game tonight I'll be starting my studying and I may be back with some more questions.
