'For Buffalo, Ottawa presents a completely different challenge than they were faced with in the first two rounds of the tournament. In the Senators, the Sabres are facing a hybrid of the two teams they beat to advance to the final four with the Sens playing the same kind of blue-collar game the Islanders played in the first round, combined with the skill set the Rangers had in the second. Nobody is playing better hockey right now than Ottawa, and Buffalo knows they have their work cut out for them if they hope to advance to the Stanley Cup Final.'
