PITTSBURGH -- Alain Nasreddine can barely contain his excitement.
As the assistant coach with the Pittsburgh Penguins' American Hockey League affiliate in Wilkes-Barre/Scranton whose focus is working with the defensemen, Nasreddine is enthusiastic about the thought of working with a projected group of defensemen that's brimming with some of the NHL's top prospects at the position.
"I've always enjoyed working with a younger D," the fourth-year assistant coach said. "Now being put in a position to be dealing with guys with that much talent -- talent that I never had as a player -- it's pretty nice."
Brian Dumoulin, Derrick Pouliot, Olli Maatta and Scott Harrington form a quartet of blue-line prospects that's likely unmatched across the NHL. None of the four is older than 21, and each was a first- or second-round draft pick. All are projected for top-four NHL roles at some point -- it's just a matter of when.
