Right you are. I think that the Sabres ability to capitalize on the opponenet's mistakes gives them the edge. It played a large role in beating Ottawa. The only game they didn't close was game 4... but had plenty of opportunities.
I've been waiting for it, but I think this is the breakout series for Big Al Kotalik. He's been playing hard and thy hockey gods shall reward him for it with some big, big goals!
