Buffalo fourth-liners Paul Gaustad and Patrick Kaleta saw plenty of ice time in Saturday's game against Pittsburgh. In fact, both of them played more than Tyler Ennis and Brad Boyes in the contest. Coach Lindy Ruff has never had the reputation of rolling all four lines for an entire game, but that could change this season. The Sabres play the most back-to-back sets of games in the NHL in 2011-12 at 21, so keeping everyone fresh appears as though it will be a priority for a team that has placed high expectations on themselves this campaign.
