The average goals-for last year among the 32 teams was 253. The Habs fell 21 goals shy of that last year.
The last time the Habs hit 253+ goals, Chris Chelios (currently age 62) won a Stanley cup, Jay Bouwmeester was #1 in ice-time, and Brad Boyes was a top-5 goal scorer. they've done it one single time in the last 27 seasons.
The Habs could very well surprise people - but you are in for a big one if you think they are going to be scoring a lot of goals this season.
The amount of goals the habs scored several years ago has no bearing on the amount they will score this season. This is a completely different team, and its the most talented team they've had in an extremely long time.
From last year's team, they will be adding Laine, Dach, and Hutson. Each has the potential to have a big impact offensively.
The young players (Caufield, Slaf, Guhle, Newhook, Roy, etc.) will be more experienced and closer to their prime.
Caufield isn't going to continue shooting at a 8.9% like he did last season.
Slaf had a major progression curve last season. Its very unlikely you see the Slaf from the first half of the season who had 2 g and 8 pts in 31 games.
The Caufield - Suzuki - Slaf were an elite line in the 2nd half of last season, and will now be together for a full season.
The habs essentially didn't have a 2nd line last season, and now they could have a really good one in Laine - Dach - Newhook.
The pp was one of the worst in the nhl last season. With the added weapons, and the previous pp coach being gone, it has the potential to improve by a lot.
Depth players like Dvorak and Anderson had some of the worst seasons in their career. It won't be difficult for them to improve on their numbers.
I don't see any forwards having major regression from what they did last season.
On defense, Matheson could have lower numbers, but that will have a lot to do with him getting less offensive opportunities because of Hutson.
As long as the team stay healthy, the potential for a huge offensive improvement is there.
