It's very troubling. We lose Trouba for 5 minutes in "defending himself". The attacker should get 5, and Trouba should get 2 for "defending". A 3 minute difference, maybe THAT will back away some, via the COACHES demands.
OR
a double minor (instigating and fighting) and NO penalty for Trouba. (4 minutes of PP) I mean, WHY should we lose him when he didn't do anything wrong? How many times have we seen this situation NOT be called correctly? If not for the great refereeing last night, this could have went the wrong way. Fortunately, we made them PAY for stupidity.
