About what I expected to see. I think the league fealt with due to the history of both the Flyers and the Flyers/Bruins this had to be. Put this in a different game with different teams and there is no suspension.
I think the league needs to mandate "SAFER" walls for all arenas. Since the players no longer worry about protecting themselves along the boards the league needs to. Since the league has started penalizing and suspending players for hits close to the boards the players no longer worry about protecting themselves. Half of them (or more) use it to draw a penalty and the other half rely on the approaching players "better judgement" to not make the hit. This way the player with the puck keeps control or makes the pass and doesn't have to worry about the approaching player. I liked the game much more when the player went to play the puck along the boards and had to keep their head up for the other player coming to hit them. When you saw somebody coming you braced yourself for the hit, then played the puck. Not just kept going about you business like they weren't going to hit you like they do now.
BTW Bruins great job of standing up for your team mates. Obviously you were going to get the 2 points anyway so why not give the Flyers a little payback....
PLEASE get rid of the instigator rule
