Players basically lost the option to lead high with their shoulder, which means that instead of hitting with one of the most heavily padded parts of your body, and impacting at a point where the least amount of force will be transferred into you, they have to basically hit core to core, which means that the hitter is going to feel it, too. Subban on Marchand a bunch of years back is the first example that comes to mind immediately. That’s still going to be a big, impactful hit, but there’s a good chance you’re going to be winded, and it takes more skill to line it up without missing and looking like a fool.
But again, those are unicorn hits and a guy like Tyler Myers at 6'8" certainly isn't capable of throwing one unless he's hitting Brian Boyle.
Generally speaking, a player skating with the puck is substantially hunched over with their head leading their body at a low height (Jyrki Lumme's odd skating style excepted). Hitting that player north-south without striking the head is basically impossible for a player with any sort of height.
