So, while guys like Makar and Hughes are talked about as the hot new trend, until we start seeing these guys have success in the playoffs, I'm not sure it's anything established.
Maybe, but if you look at the top 4 teams in the NHL let's just say point wise, Colorado, Florida, Carolina and Toronto....this is what you end up with let's use 25 GP as a base,
Bowen Byram - 6'0 - 194lbs
Samuel Girard - 5'10 - 170lbs
Erik Johnson - 6'4 - 225lbs
Jack Johnson - 6'1 - 227lbs
Cale Makar - 5'11 - 187lbs
Josh Manson - 6'3 - 224lbs
Devon Toews - 6'1 - 191lbs
Some big guys for sure in Johnson and Manson but that's it,
Florida
Ben Chiarot - 6-3 - 234lbs
Aaron Ekblad - 6-4 - 215lbs
Gustav Forsling - 6'0 - 186lbs
Radko Gudas - 6'0 - 204lbs
Brandon Montour - 6'0 - 194lbs
MacKenzie Weegaer - 6'0 - 200lbs
Robert Hagg - 6'2 - 204lbs
Again, only 2...
Carolina
Ethan Bear - 5'11 - 197Lbs
Ian Cole - 6-1 - 225lbs
Tony D'Angelo 5-11 - 180lbs
Eric Gelinas - 6'4 - 190lbs
Brett Pesce - 6'3 - 206lbs
Brady Skej - 6'3 - 210lbs
Jacob Slavin - 6'3 - 207
Brendan Smith - 6'2 - 200lbs
I'll admit I'm surprised Carolina's D is that big, I thought they were smaller
Toronto
TJ Brodie - 6'1 - 185lbs
Mark Giordano - 6'1 - 200lbs
Justin Holl 6-4 - 210lbs
Timothy Lillgren - 6'0 - 198lbs
Ilya Lybushin - 6'2 - 201lbs
Jake Muzzin - 6'3 - 217lbs
Morgan Reilly - 6'1 - 217lbs
Rasmus Sundin - 5;11- 183lbs
Now granted, you did mention playoff success, but for now, the 4 best teams, do not have an imposing defense, size wise, what they do have, is the ability to skate, and move the puck.
