The top line isn't the reason for the Penguins' 5-1 loss to the Blues. The Penguins as a whole just didn't match the Blues' approach.
But, man, it's rare to see that top line have an outing as rough defensively as this one, and Sidney Crosby, Jared McCann and Jake Guentzel were on the ice for the first three goals against.
"Two of (the first three goals) I thought were avoidable, one of them I think they got a little bit of puck luck," Mike Sullivan said in his postgame press conference. "That line has been great for us. They're three guys that have played so well for us, and I think we've got to do a better job on two of them on making sure that we come back, and we don't get beat back up the ice and we stop and defend the scoring area."
Which goals are Sullivan talking about? Let's break it down.
