Fire Peters. Change the defensive system to one that doesn't lead to so many odd man rushes. Trade Faulk for something. Buyout Darling. Target Dell, Raanta, or Grubauer for a trade/signing.
A few things that stand out to me with how our defense plays. These are just observations and not necessarily all problems or bad things:
1) Always tight gaps and aggressive pinches. While that helps maintain possession and makes it hard for the other team to get any flow, it leaves precious little room for error (thus the odd man rushes). Bruins had more than a few last night but also had a stretch in the 2nd where they went a long time with only 1-2 shots. It works both ways.
2) They hold onto the puck a long time when trying to come up the ice out of their zone. Whether it is a guy skating with it, or passing it D-D until the forwards clear the zone, there is way too many times where the forwards are left standing in the neutral zone which kills any flow and then ends up as a dump and chase. Unless it's a Slavin stretch pass to Aho, the Canes rarely get a breakaway or odd man rush these days, except for situations like the PK last night. Maybe that's on the forwards as well where it seems only a few (Aho for one) are able to circle back to maintain momentum rather than do like others where they get to the blue line and stop.
3) They aggressively join the rush, sometimes before the team even has good possession. Then there's a turn-over and an odd man rush. I'm not suggesting the D shouldn't join the rush and it's easy to second guess when it goes bad, just sometimes the decisions seem off.
If the defense was contributing a ton of offense by playing this way, that would be one thing, but the team, IMO, is under-achieving in this regard based on the talent the have.
