I don't agree at all. The biggest reason he was invited to this thing was because he was infamous; the focus was always going to be on the thing that made him infamous. Keep in mind that that incident was huge news in Vancouver - for days after it happened and then again when it wound up in court. A lot of people would have wanted to hear him talk about it. As for the interviewers going too far, if McSorley doesn't act like a victim, that line of questioning would have petered out on its own. Arguing that he didn't hit Brashear in the head, that Brashear was a coward, that that one guy over there agrees with him ... that's the kind of thing that will just lead to more questions.
Again, had he just said: "I was trying to get him to fight and I didn't mean to hit him in the head. I feel bad about that. I'm glad he didn't end up with a long-term injury, but I was careless and it happened." Then to the question of whether he's spoken to Brashear: "No, the truth is I never had much of a relationship with him before that happened. Fighters often develop a level of mutual respect, and so I have good relationships with some guys, but Brashear and I never developed that relationship. Nothing against him, but we just don't."
He does that, and the interview probably pivots to other stuff.
Here's the thing. McSorley was paid for his appearance at the Giants game, and part of the contract was almost certainly that he do media in advance. That he wasn't prepared at all for even a couple of questions about this just completely boggles my mind. I assume he has an agent who would have booked this. Why they wouldn't just do that basic legwork - I can't figure it out.
The really funny thing is that a tamer interview probably would have not gotten nearly as much attention. I don't know if this clip got shared around in Canucks social media circles, but if it did, him being defensive would have been shared a lot more frequently than him just being straight up or him not being asked about it at all. If the intent of media is get attention and drive people to the rink, asking him a bunch of questions that didn't get a reaction would have been worse for the promotion that he was hired for.
