Who steps up in the playoffs?

To determine who steps up their goal scoring in the playoffs, I compared the regular season goals/game to playoffs goals/game for all skaters in the current post-season. There appears to be a significant drop off in goals per game attributable to the tighter play, fewer power plays and better competition, slightly offset by the greater amount of ice time due to overtime. There are less than 20 playoff veterans who step up their scoring in the post season. Everyone else trails off in crunch time.
