Not trying to be difficult or prolong the discussion over this one play, but there is a lot here I simply don't agree with.
1. Scandella is covering the pass to Dach, but he has also been left in the unenviable position of covering the pass to Saad as well.
2. Prior to either of the stills you posted, Faulk was much further over to the far post, taking away a pass to that point. That's not "covering a ghost" that is getting caught in transition, which you and others have pointed out is likely due to poor communication.
3. If Sunny and Barbie were truly "covering the point men" they would both be further out, which would actually be more disastrous. They're not positioned to defend a point shot and they're not positioned to prevent a pass to the point. They're just there.
4. You referred to Faulk as "covering a ghost", but who are Sunny and Barbie really covering? I contend that the answer is "no one", which to me is the biggest failure of this coverage. Any pass back to the point is almost certainly going to go off the wall or via Dach, giving either of them time to turn and press their point man and further process and decide what to do next. Both of them have the play right in front of them and both can clearly see that until Faulk starts to move from the far post back to the top of the crease (too late as it turns out) Saad is completely uncovered. Again, probably bad (or no) communication, but in my view one of those two has to drop lower and either put a body on Saad or at least get in a position to tie up his stick. Faulk being on the far post was the only option to prevent a clean pass back to the far point man (Barbie could not have reached even a direct pass from behind the net without shifting even further out) and Faulk only left that preventative position when Strome clearly committed to moving the puck out from the other side. About the only thing I think I can fault Faulk with here is not processing the fact that, as a left shot, Strome was about 90% going to move the puck back out on Scandella's side and the other 10% would have required Strome to take the time to adjust his positioning to make a pass back to the other point, giving the defense time to react and adjust. In that sense, he could have covered Saad and (maybe) had enough time to react if Strome reverses to an outlet on the other side or a move above the goal line, but Sunny and Barbie are literally doing nothing else in these frames so I feel like one (or both) of them should have covered the net front.
