As dissapointing as the season has been, it's been difficult for me to be too hard on Lambert. Let's look at the roster he inherited: Best goaltending duo in the NHL, very very good D core, and bottom 10 forward core.
He implements a system that attempts to help out the team's offense by constantly activating the D men - the upside of this is a boost in scoring (our D has scored the most goals in the league) at the risk of leaving your goalie out to dry. Fortunately, as previously stated you have the best goalie tandem in the league, and your starter is leading the league in GSVA and has a top 5 save percentage despite the increased high danger chances.
If your defense is scoring at the highest rate in the league and your goalie is top 5 in save % and GAA, shouldn't that be enough? Unfortunately the forwards still just can't score. Even with all that scoring from the defense, the team is in the bottom quarter of the league in goals per game. Add to that 2 of your top 6 wingers go on IR for an extended period of time. PLUS your top defensive player misses 20 games.
Just feels hard to put this on Lane at this time. The blame should be directed towards Lamoriello for being unable or unwilling to provide the team with the scoring boost they so obviously have needed since he arrived.
