After watching all the post game player interviews and Boucher, I'm feeling a bit more optimistic. I know, it's probably unwarranted. But they seem to have gotten over the insert cliche of your choice about getting chances and so on, and have gotten to the point of taking a hard look in the mirror and not liking what they're seeing.
Last night's postgame interviews wasn't a matter of players and staff suddenly lifting of the veil, suddenly realizing they'd been duping themselves; they looked genuinely shaken.
In a number of the games past, much of the underlying fundamentals were at least encouraging. It was isolated poor performances (i.e. a skater struggling for a stretch of the game, subpar goaltending) and periodic breakdowns (turnovers and positional mistakes) that opponents
seemed to be converting at an abnormally high rate, especially early in games, that, when combined with an anemic power play and an ability to convert on most of the high-quality scoring chances they earned or were handed to them, helped explain the poor results. The bad was easy to spot but some of the results (bad bounces, sudden propensity of posts, missed nets, etc.) were somewhat mystifying. Hence the fairly positive message you heard game after game.
That wasn't the case last night. They didn't spout off about missed chances being there because, for the first 40 minutes, there really weren't any as the Lightning were busy being unconditionally steamrolled. It wasn't until the Rangers essentially went into a prevent defense that the Lightning were able to mount any significant offensive pressure. With the exception of Garon, there wasn't much, if anything, else to hang their hat on.
