I see now it's likely RT had the team playing Rope a Dope against the team that was playing it's 3rd game in 4 nights on the road. Still doesn't explain how we couldn't keep the puck on the stick until then. Or why three times we left a guy in the slot free to get a pass. This is where Demko really shined (shone?).
But after seeing Swayman in OT I see now why so many teams have taken them to OT. For all of his size, the Bruins collapse in front of him when on D.
In OT, with all that room, they can't do that and he's very vulnerable.
