A record-setting defense carried the St. Louis Blues to the Central Division title in a breakthrough season. When they can pair a potent power play with a stingy, tight-checking mentality, they truly are tough to beat. Patrik Berglund scored the first of St. Louis' three man-advantage goals, and the Blues throttled the San Jose Sharks until the closing minutes of a 4-3 victory in Game 3 of their first-round series Monday night to take a 2-1 series lead.
