The Western Conference teams have had the advantage over the Eastern Conference teams since the start of the 2005-06 season, but it's been even more pronounced this season, leading to various theories as to why that may be.
There's the element of speed, which many coaches, especially in the Western Conference, believe gradually has gotten better in the West over the years. There's the depth up front, especially among the top-two scoring lines on each team, which coaches talk about that being in favor of the West.
"We played Detroit and their top line killed us, but there was no secondary scoring," Dallas Stars coach Lindy Ruff told NHL.com. "Buffalo has had a real tough time scoring and we played against them. Montreal at the same time was having the same type of problems. I would point to that."
St. Louis Blues coach Ken Hitchcock doesn't disagree with any of it, but when asked for a reason why the depth and speed appears to be greater in the Western Conference, maybe greater than ever before, he said it's a result of the measuring stick the Western Conference teams have now that has nothing to do with the Eastern teams.
