Depth charge

A big part of the Bruins' early-season success is their ability to keep rolling out fresh lines of skilled players. Marc Savard (left), who is currently third in the NHL with 25 points, centers the top offensive unit that includes Lucic (center) and Kessel (right), but Bergeron's line, Krejci's line, and even the defense-minded fourth line of Thornton, Yelle and Chuck Kobasew can skate, shoot and score.
