I did read that in the interview you posted a few pages ago, the same one where Miller said the following:
“This isn’t about saving my career. Obviously, I want to play hockey. It’s my dream, but I want to let everyone know that I made a mistake and how sincere and sorry I am that I affected their family and their lives. I got dropped by Arizona and North Dakota, but it’s not about saving my career. It’s letting people know what I did was wrong. Again, I take all ownership of what I did and I’m not going to defend myself on all of that stuff.
“At this point, I think the debt-to-society part is like 10 times more important than my hockey career,” he said. “Hockey would be a reward if I could ever have a second chance to have that back in my life, but I want to give back to the community.
Here’s the thing - even in the absence of talking to the person he bullied directly, there are many things that Miller could have done to give back to the community in the year between this interview (where, as you say, he wasn’t allowed to talk to the kid he bullied) and getting signed by the Bruins.
So. What did he do? Aside from get in touch with the kid he bullied to apologise because the Bruins told him he had to, that is? [ed. This is a rhetorical question, because there are some team activities listed in the interview that Miller participated in, but if you’re the guy with the baggage, you have to go above and beyond the rest of your team].
That is why I have some doubts.
