I'm not seeing your first point - but I do see the second.
Forwards are likely on the walls because that's where everything comes from - our D like to wrap it around and hope for the best.
This isn't a strategy - this is the result of being unable to handle play in our own end. By the time we get the puck back, they simply want it out of the zone - call it panic.
There is no way in the world this is by design
Moose play the exact same way so yes it is by design. The Moose do have a good defense and generally are able to hit the forward on the side in stride so they get it out easily. But everything goes up the side for them as well, it most certainly is the teams breakout strategy, it's just that the Jets don't execute it very well.
Part if that is the M2M pulling our players out of position so our breakouts can be disjointed. Moose play more zone in their end so forwards aren't being pulled out of position and are able to get the puck in good spots.
