The NHL Experts blog is a collaboration of voices from around and inside the game of hockey. With viewpoints ranging from the press box to the front office, the Experts blog will offer unique perspectives through the playoffs to keep readers informed of significant storylines in all aspects of the game.

Let's start by saying this: Tyler Seguin has been great for the Boston Bruins, adding scoring punch in the early-series absence of Patrice Bergeron and keeping it going in Bergeron's return. In Game 2, Seguin, 19, became the first teenager to score four points in a single period in the NHL playoffs, and the first player of any age to do it since Alexander Mogilny did it with the Devils in 2001. In Game 3, Seguin scored again.

But let's also say this: Comparing young forwards and defensemen in the NHL is like comparing people years and dog years. Defensemen typically take years longer to mature, simply because the position they play is more nuanced than that of the guys up front. Which is why, even in a Tampa Bay Lightning loss, Victor Hedman is so impressive.
