I don't think it's at all hyperbole to say this year's team probably has some of the worst metrics in the league in the opening 10 or so minutes of games.
Not only do we give up the first goal so often and many times in the opening minutes, there's been so many times this year where shots are like 8-2 or 13-5 or some shit either in the 1st period or first half of the 1st period. I think 8-2 was something from last game, before shots were about even to end the 1st.
And it's been happening with healthy lineups and not only against good teams, but some f***in awful teams too, like your Arizona's, Montreal's, Washington's, Columbus (first time we played them) and some other particularly poor teams.
I remember going on about this as far back as October. It was happening back then (we played 3 of those teams in the opening month) and we had mostly healthy lineups back then.
