I think it's great, and necessary to have 2-3 guys on a team that will throw them when necessary. And you need a heavy weight among them.
I was never a fan of an enforcer only guy. Hated it. That's why I lived a guy like Nuckles Nilan, who could fight , but also play hockey and produce some points.
Wifi can fight. But he can also hit, skates fine and also has ability. His TOI has gone up every single game this year and that's not because he fights. He makes mistakes, but he does good things out there also. He has the makings of some offensive ability and he will pinch in, which surprised me.
To me he seems a much bigger, faster and more skilled Lyle Odelein. I think , based on the 6 games so far, that he could be a no.4 D man in time.
