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!
