Sam Weinman at the Rangers Report looks at the reasons for the Rangers fast start to the season including goaltending, favorable schedule and coaching among other factors.
...i don't want to take any credit away from the players for their outstanding start to the season. But I think the biggest reason is the favorable early season schedule. Being able to rack up wins against some very sub-par teams (Tampa, Islanders and Columbus) has kept the fans, many of whom were not happy with the off-season overhaul, at bay allowing the team to gel and new players to get comfortable in New York. Could you imagine if this team started on the road in Colorado and Minnesota then came home to play the Canadiens and Penguins possibly starting 0-2-2 or 1-3-0? The fans would have been all over this team. Especially newcomers Redden and Naslund.
...having said that, I really don't care what the reason is, I'm just happy with the results.
