Scores will never reach what they were in the 80s because goal tending and coaching have evolved way more than offense has since then.
I'll admit that I've never been a goal tender, but I would make 2 changes if I could. I would actually increase the amount of pads goalies can have on the inside of their legs. My understanding is that this will decrease groin injuries. I could be way off on that, but that is what I've heard and it makes sense to me.
I would also wrap the outside of the leg pads around goalies' legs rather than let them be a big square surrounding the front of their legs. Leg pads should protect the legs and 5-hole to me. Leg pads now look more like blockers than the look like pads to protect legs.
Also, how does shrinking the width of pads put goalies in more danger? As long as the padding is just as thick as before, what effect does it have? I'm not asking this as a challenge. I'm just curious since I've never played the position.
