The Nashville Predators have a pretty simple philosophy when it comes to drafting defensemen. They need to be mobile, they need to be able to pass with high efficiency and they have to be active offensively. Because of this, most of the Predators' attack starts from their defensemen's ability to move the puck out of their zone with a crisp first pass. But through four games, Nashville's blueline has found itself on the outs of its offense, which caused some concern to Predators coach Barry Trotz after Nashville's 3-0 loss at St. Louis on Thursday. "Your 'D' is involved when you get out of your end, when you manage the puck through the neutral zone," Trotz said.
