Your first 2 statements are directly opposed to each other -- once you get into the Conference Finals and Cup Finals, the matchups become evenly matched practically by definition. An elite 4th line CAN be the difference to winning those series.....and thus a Cup.You don't win cups with an elite 4th line.
A quality 4th line can be the difference in an evenly matched playoff series for sure. But when the top 9 forwards and top 4 D aren't up to par, a great 4th line is polish on a turd.
However, you're absolutely right that an elite 4th line means NOTHING if the higher-up talent on your team isn't up to snuff.
