I have heard this argument, but I don't agree.
As you said, people can theorize all sorts of things, but it is much more likely that athletes today are larger, faster, stronger, and are more aware of technique that enables them to dish out more punishment on opponents. I can't imagine how equipment could possibly trump the energy that comes with the competitive endeavor.
