*they have achieved the same result as the Sabres thus far.
The Sabres have been outshot by 314 though 29 games - a, average of 11 shots per game. Dallas is "only" -19 in shots.
Buffalo has been on a nice run, but Dallas is still a better team.
You are obviously not looking at the games they are playing. Buffalo is forcing the opponents to take lousy shots, which is why Enroth has so good save% aswell, he takes a lot of easy shots. And the opponents can't convert them into enough goals since they are forced to make those lousy non-threatening-shots.
Buffalo scores more goals than their opponents, they convert their chances so obviously they get better scoring-opportunities than their opponents.
In short, Buffalo is winning because they score more goals than their opponents. Simple as that, since that is the foundation of the game. No matter what statistics is saying, Buffalo is winning games.
