The longtime season-ticket holders behind the Buffalo bench will undoubtedly do double- and triple-takes tonight in First Niagara Center. After 16 years of looking at Lindy Ruff and his designer ties, they’ll see Ron Rolston and his Burberry glasses. It’ll take some getting used to for everyone involved. The Sabres learned that quickly during Rolston’s coaching debut. The forwards heard a new voice handing out assignments and sending them over the boards Thursday in Toronto. Though the transition from Ruff to Rolston went seamlessly — the Sabres weren’t penalized for too many men and never missed a shift change — it was different. “It’s just awkward when you hear a different voice,” Sabres captain Jason Pominville said. “Lindy’s been a leader of this organization for 16 years, so he’s been the guy that everyone’s been used to hearing, whether it’s on TV, in the media or in the locker room. “It’s nothing against Ron. It’s just different. It’s going to take a little time for everyone.” The problem for the Sabres is there’s not much time left to salvage this season. They welcome the New York Islanders to town tonight as one of the NHL’s worst teams, one that has lost three straight and eight of 11.
