One key component for this D to work is how you angle your guys to work in unison with each other. The goalie rod man should be angled slightly forward and the two rod should be either straight up and down or just angled very slightly back. The sense of sight and the processing our brain does is a wonderous thing, but sometimes it plays tricks on us that I will show you later with an illusion.
The slight tilting forward and back of the men presents depth perception problems that most people don't even realize are going on. For ex., stand as if you're about to shoot. Now pull the two rod to you in the dead position with the guy toed out. It's obvious to you the guy is in the long because your eye will focus on the foot of the man. Now tilt the guy back say 20 degrees or so past vertical. Because your eye still focuses on the foot, it seems as if the man has moved slightly out of the long hole because of the "perception" of the foot in relation to the goal even though you know the man has not moved at all. This is how good goalies get in your head by changing the perception of what you see by making you shoot at what seems there but really is not.
One of the best compliments I ever received was from one of the sport's greatest pull shooters. Ask Ed Geer about Hossein Kiani. Show him a post and the ball disappears off the table. However, I had good success blocking him with a post defense. But... I blocked him with a post guy tilted back. I later asked him why it gave him so much trouble. He told me that when most people post him, the foot was pointed forward so he knew exactly where the man was so all he had to do was hit his dead stroke. But when I tilted the guy back, he could not read exactly where the guy was, long or 3/4. So he would not use his dead stroke, he would just try to beat me long of which I was waiting for him. In other words, he concentrated too much on the long and not the rest of the goal because of what he thought he saw.
So remember, two rod tilted straight down or slightly back with the three rod tilted slightly forward with men a ball width apart and BLOCK THAT CIRCLE.
Here's that illusion.
