I don't agree with the above statement. I don't see how guys would need to be stronger the bigger they get, especially in a game like hockey where you're carrying your mass on skates. Being ten pounds heavier for each inch gained in height isn't a huge difference by the way. If you checked the prospect combine, you'll notice that size isn't a big factor in a the strength test. Both big and little guys will show up in the top ten for strength test.
I can understand that it can be a bit hard to understand, but its definitely a fact. Have you ever seen a 6'6 hockey player just in general move like a 5'10 player? I've watched hockey for over 30 years and never seen it. The movement pattern is just different. We will never see a 6'8 forward that moves like Sean Dooghe. There is a reason for it, and its basically simple fundamental physics.
The bigger you get, your weight increase exponentially. A human being isn't built as a sphere, but to illustrate the fundamentals behind the physics, the volume of a sphere with the radius 1 is 4,19, and the volume of a sphere with the radius 2 is 33.51.
As a result, the bigger you get, to move your own body, you must proportionally be stronger.
On the flip side, the bigger you are, the harder to move you will be. You are heavier. You will get pure force behind hits. Everything you do basically. But in relation to your own body, you will be weaker.
Hockey isn't a very stereotypical game. There are and have always been room in the game for different type of players, and that will of course also always be the case going forward. But in general, I think its hard to come to the conclusion that the average forward would benefit from being 6'3 instead of 6'0.
