There really is no short cut to 3 person. You have to review the mechanics and know the terminology. If you do not know the terminology IMO and the basics, no one is going to be able to correct you very easily. You have to be a student of the game like knowing what the difference between a rotation and a switch. We can tell you where to go after a foul call, but if you do not know when to make a call in your primary or outside of your primary or what to do in a double whistle, it is going to be useless to tell you anything. And even with the NF or local standards, there are a lot of exceptions and situations that you just need to see or experience to know what is acceptable. The best example is as the lead calling a play coming to the lane when to know when to have a whistle and when not to have a whistle. And depending on where you live, there might be some different philosophies when that should take place.
