At that point in the game the Sens were down a goal and needed to score more than take a penalty for instigating a fight. The next time the Sens and Jets play is when the fight will happen. Also, do you really think Trouba would accept a fight with Neil? And do you want Neil on the ice with 9 mins left in a game where you are down a goal and all he is doing is chasing Trouba around the ice rather than trying to help his team win? Side note, having an enforcer does not stop hits like this from happening. You think Trouba had even one split second of a thought of, "Oh man, Chris Neil has been on the bench for 56 minutes of this game. Maybe I shouldn't throw this hit because he might get a shift and challenge me to a fight!" Next game is when Trouba gets punched in the face.
