That has little to do with a goalie's equipment. Imo, if equipment size is reduced, a lot more of these crash and whack goals will occur than "skill" goals.
I think, if you reduced the width of goal pads, shrunk the blocker, and reduced the size of the glove, you'd be seeing more pucks sneak into the net off clean shots. The size of goalie gear isn't the sole factor in the reduction of offence from the 80's and early 90's, but it is a factor.
I hear that a lot about goalies from younger fans looking at video from the 80s. People look at the 80s and have a certain perspective regarding it. I remember an Oilers team that was very innovative (on top of their skill). They would intentional draw coincidental minors to get 4-on-4 play. Their line changes were designed around speeding up their transition game. That neutral zone drop pass that Canucks fans are sick of seeing was used extensively by that Oilers team. Skill and tactics is how I believe this "problem" should be solved.
Well, I'm not sure how "young" I am. I'm 36. I agree with the most of the above, but I'm not entirely sure what that has to do with having more net to shoot at. A shot from the top of the circle used to be considered a scoring chance. That's not the case now. Yes, goalies are better, but they also take up more of the net.
Now, I'm not suggesting smaller goaltenders or bigger nets is the be all and end all, there are other factors at work that are hurting the amount of offence in the game. Better coaching, better systems, better players are all factors. But in my opinion, having a little more net to shoot at couldn't hurt the entertainment value of the game, could it?
