I was at the game last night. I cannot excuse whatever Ivan might have said. He did get an Unsportsmanlike Conduct penalty with 45 seconds to go, for what it is worth, on the scoresheet.
However, this really started to go downhill when Cole Perfetti scored the empty netter. Actually, a little before that even. Knights #80 (Alex Formenton) was looking to layout somebody whenever he didn't have the puck. As the puck was going into the net, he had enough and shoved a Spirit Player (I cannot recall who) while he and others were raising their arms in celebration. So he got the gate after the puck went in for roughing. This is all with 2:14 second left.
Play started with the Spirit on the power play. They advanced the puck, got down low, took a shot that was blocked, and bodies starting getting shoved around. This lead to 4 players (2 from each side) going into the box and Knights #16 (Kevin Hancock) sent to the locker room with 1:38 seconds left (game misconduct). So within 36 seconds, we got 5 guys in their respective penalty boxes.
At that point, I believe the Spirit did the right thing and just not advance the puck. Take a knee, run the clock out, whatever, because it did not look like anyone was playing hockey anymore.
