There are many people who feel the shoulder pads with the increased chest guard are actually more dangerous. The theory is the impact of the shot is distributed throughout the chest and not just isolated to the area impacted. One thing is sure, these types of injuries need to be studied to get a better handle how to prevent.
I have never heard that about shoulder pads with a better heart guard protection is more dangerous. Thats says strange, I'm not saying I don't believe your research it just sounds strange.
