I highlighted the word "fix" because it's entirely inappropriate and demonstrates a lack of understanding regarding hockey strategy on your part.
Collapsing defense is a hockey strategy. It's not a mistake, it's not wrong, it's a strategy. One that has worked quite well
at times I might add. High pressure D can be picked apart by quick puck movement. It can lead to high quality scoring chances. This is something the collapsing D avoids. No easy scoring chances, keep everything from low percentage areas. You're INTENTIONALLY conceding certain areas, the bad scoring areas. You don't like defensive breakdowns? You'll hate high pressure D.
Carry the puck into the zone more. Like torts was telling guys, even if you can carry I want to see a dump out there! Yeah, no. That wasn't happening. Torts just preached responsible hockey. Don't try some low percentage carry with a high chance for a neutral zone turnover and a quick break the other way. This is hockey 101. For all styles of play. Thing is we don't have good puck carriers, that's why we dump so much.
This last point is perhaps the most nonsensical of a nonsensical list of "fixes". We would dump and change instead of dump and chase when it was time for a line change. We'd chase a dump when it wasn't time for a line change. You see in hockey, you often have to change lines on the fly. So, in order to prevent odd man rushes against you or to prevent leaving your team short in your own zone a common practice is to dump the puck into the other teams zone (hopefully all the way to the wall as far away from your own net as possible) and change so you won't be leaving yourself vulnerable to the other team's O.
All of your "fixes" would be detrimental defensively.
