Maybe. Maybe not. This years draft somewhat resembles 2013 at the top end. If you got MacKinnon or Barkov that year you'd be laughing. If you end up Seth Jones or Elias Lindholm you may not be as happy but at least you got a useful player. If you end up with Jonathan Drouin...
That remains to be seen, but Dach only put up 1.35 points per 60 in 5v5 play last year. That's on par with a good 4th line player and below what cap dumps like Dvorac, Drouin and Hoffman managed to do.
You can stat watch all day but it doesn't change the fact that Dach showed significant progression offensively this season and finished the year as the 2C with crap wingers, yet still drove play.
But if you want to stat watch: Dach is going into his D + 5 season. PLD in his D + 5 season put up 21 points in 46 games. Barely a 3C.
Habs are happy with Dach at 2C and will give him the opportunity to build on last season. They traded significant assets to get him and he has rewarded the Habs with his progress. No reason to turn away from Dach and give up significant assets and then overpay for a 2C in PLD.
The only way you build a competitor is to develop from the draft and the Habs are doing that. The time to swing on trades like PLD is in year 4 or 5 when the holes in the lineup are more apparent.
Signing PLD to a 9M longterm deal had disaster written all over it. You just don't do that when you are rebuilding and have assets in-house that are well on their way to becoming a 2C or better.
As a Jets fan you will learn the intricacies of a rebuild after this coming season.
