Looks like more often than not, we are not scoring enough.
Not sure if keeping the same guys is the right answer, it worked for a couple of teams (mostly Colorado/Washington) and hasn't worked for tons.
I don't think there is a secret formula to winning the cup, but at least in recent years, all of Nylander/Marner/Matthews are PPG and playing well, the myth that they are playoff no shows comes from their younger years playing teams that were super defensive or had great goaltending (Bruins, Columbus, Montreal).
