Dach isn't an enforcer but he had fights in the WHL and also previous fights in the AHL. He's had enough of them to know what he's doing, He's had at least one instigating situation so it's not like he's unwilling.. From the fight replay it seemed he didn't like Kasper getting his stick up on him after a hit at the blue line. Although it's off-screen Dach probably went back at him and Kasper complied rather than skate away like a p***y who'd rather just take it easy late in a game they were losing 4-1. What's the point, some might say, especially if the other guy is a lot bigger. I find this consistent with what we know about Kasper and an admirable characteristic.
