St. Louis GM Doug Armstrong likes what the addition of Derek Roy could bring to the Blues' roster. "We have bigger players, we have scoring centermen, we were looking for a playmaking centerman," Armstrong said. "I think Derek adds diversity to our group of forwards. When you look at the centermen we've had in the past, maybe size down the middle was one of our strengths ... we have [David] Backes and [Patrik] Berglund, they're big men; we have a different component in Derek. We're hoping he's going to create offense for players like Chris Stewart on the wing." Roy got a one-year contract from the Blues in July, so he could be motivated to secure a longer term deal for himself this year with a strong showing. He is projected to play on one of the team's top three lines.
