Yes. Demidov change everything. The rebuild is more perfect than expected by drafting him. That's a great moment to be a Habs fan. We are going to have a amazing team for many years to come!
He was the last necessary piece in the rebuild. Almost everyone here was expecting someone who could lead a 2nd line or complement a 1st, not someone who can be the best player on a cup contender.
Here's my 8 player profile (excluding goaltending) to be a perennial cup contender. I'm also going to give their comparables for the Chicago Blackhawks dynasty teams.
No 1 C - Suzuki (Toews)
No. 2 C - Dach (N/A)
Power F - Slafkovsky (Hossa)
Star F - Demidov (Kane)
Specialty F - Caufield (Sharp)
Two Way D - Reinbacher (Keith)
PMD - Hutson (Seabrook)
Shutdown D - Guhle (Hjalmarsson)
If Habs can add good depth to surround this core, sky's the limit
