BUFFALO — Right now, there’s a forgotten man on arguably the NHL’s deepest blue line. Never mind he just scored 13 goals, led the team in ice time and enjoyed a career season. The Sabres have newer, shinier and younger defensemen grabbing all the attention.Leopold scored 10 goals through last January but faded down the stretch, conceding offensive minutes to Andrej Sekera and Marc-Andre Gragnani. Expect him to approach 30 points this season but he will need to now compete with Christian Ehrhoff, Tyler Myers, Gragnani and Sekera for offensive minutes.
