I think this is a major part of the defensive structure. Most of the blue line are tall guys with long sticks. No easy entires into the zone because they are active with the sticks in lanes and blocking passss or poking it to create a turnover that a forward in support to carry it back the other way.
So this has lead to teams dumping pucks in against the devils, and the biggest improvement to me this season has been there ability to go D to D below their own goal line and safely exit the zone. So frequently in previous years the D would be caught behind their own net trying to retrieve pucks under pressure and turning it over. Happened constantly last year. This season, it doesn’t happen very frequently, but the times where the devils have given up bad goals it’s because of this. Happened the first couple games against Philly and Detroit, and caused the Tavares goal in the Toronto loss.
It’s been a thing of beauty to see sieg go back to retrieve a puck below the goal line under pressure. He absorbs a hit while poking it to Doug so he can carry or fire it up the boards for a safe exit. Really has been a major difference for results. Along with competent goaltending, the defense plays with a lot more confidence now.
