It's a little bit overwhelming seeing this kind of reaction to my arrival, but I guess I'm prepared for it, ... I heard that there was a lot of excitement in the city. I heard how Pittsburgh was a great sports town.

For the first little bit it was awkward, but it's okay now,

Concussions are still kind of a mysterious thing.

I think every athlete will tell you no matter what sport you're in, when you train so hard and when you care so much about doing what you do, there's a little bit of nerves that come with that. But nerves that won't prevent you form performing, nerves that, hopefully, allow you to be that much more motivated and inspired to do well.

In football, every play, play after play, there's that physicality. Football players only play once a week, so they must really need to rest. That does kind of tell you how physical the sport is. But in hockey, you have the boards. I just couldn't say which is more physical.

I'm really excited about London and seeing everything that's there. I think it will be overwhelming.
