I think its more that the m2m scheme they run pulls everyone all over the place in the dzone and due that we often don't have numbers back defending the house. Its easy to get to the front of the net within the team you are playing doesn't have bodies back. I think clearing the crease would be more effective with a boz plus 1 scheme where you always have that box shielding your net and preventing players in.
The game today the goal was on an isolated 1 on 1 battle where their player committed and infraction and got away with it.
IDK - maybe there is an impact but the obvious issue appears to be our inability to move players
And don't forget the goal where they were allowed to stick handle in our crease - how do you allow that?
As for a box set up shielding your net - how does that work when we are unable to shield our net? Players are walking in and planting themselves there and our D are not stopping them.
Add the center if you want but in the end, you usually have a Dman in front that is dealing with a one on one situation in front - and we lose most of those battles.
Our blueline is small - and the majority of the small guys are more offensive (new age) dmen who do not handle traffic very well at all - I don't see how this is even debatable.
