I remember playing pick up with Janssen and a few other Junior B players of the St.Louis Sting back in the day. He was a few years younger and only 5'5', a bit of a runt at the time. I remember this because he was the smallest young guy out there but at his young age was fearless about getting into someones face twice his size. This showed character that has lasted him through the process of making it to the NHL. Win on aggression for Janssen.
