I'm kind of neutral to it. It can be amusing and is sometimes very warranted, but it could be banned tomorrow and that wouldn't affect my enjoyment of the sport in the slightest.
I'd prefer McIlrath show what he's got in the hopes that he cracks the lineup at some point this year, or next, and I think his fight against Labrie wasn't all that necessary...
But I'm not going to mind in the slightest if he steps up to shut down some fiesty Flyers. Particularly after Simmonds' comments. Flyers/Rangers fights are always a possibility, if not a probability, pre-season or no. Some real hatred there.
