The Devils don't control the length of the season. As it is 48 games and not 82 games, they'll probably miss the playoffs - hockey-reference's forecast has NJ at 22.6% to make the playoffs, Sportsclubstats at 19.0%.
So I decided I'd go through and make a list of things that, had they gone slightly otherwise, NJ would be at least 50% to make the playoffs. I'll use stats.hockeyanalysis.com to check out the numbers, using the basic standard of 5 goals = 1 win.
The Devils have shot 6.4% at 5v5 even strength - NHL average this year looks to be about 8.1%. Had they shot 8.1%, they would have had 13 more 5v5 goals or at least 2 more wins.
The Devils have shot 10.5% on their 5v4 power play - NHL average this year looks to be about 12.6%. Had they shot 12.6%, they'd have 3 more goals, or 1 more point.
The Devils' goalies have stopped 83.7% of shots on their penalty kill. Had they stopped the NHL average of 87.4%, the Devils would have allowed about 5 fewer goals on their penalty kill, or about one win.
The Devils are 2 and 7 in shootouts. If they were 4-5, they'd have 2 more points.
The Devils are 1 and 3 in overtime - if they were 2-2, they'd have one more point.
Had all of these things happened - and all these things mean just being average, they don't even have to go over the average (I suppose we can dial back NJ's shorthanded goals by a bit too, docking them a full win) the Devils would have 8 more points and would currently be in 5th place in the East, comfortably in a playoff spot.
All of this is a way of saying that if this were an 82 game season, this would likely be a blip. The goalies aren't playing particularly well, they can't win a shootout, but they're playing excellent hockey. Of course the Devils would have made the playoffs with Zach Parise and this set of circumstances - but the way the team is playing this year is giving me plenty of hope for the team without him.
