When guy's get bigger they have more explosive, stronger take downs and scarier striking power and they lose a little bit of quick in and out speed like Edgar shows. (which is what makes him potent)
The heavier you get the more dangerous things are and that's why people perceive heavier guy's as having worse technique when they get dominated.
I can watch fighters and evaluate their skills. Edgar, Cruz, and Aldo all have superior technique to GSP and a natural rhythm to how they fight that GSP lacks. GSP has great timing on his takedowns(Not as good as Cruz) but when he is striking or on the ground he looks like a robot and is clearly over thinking everything he does. GSP flat out does not have the defensive or offensive striking skills of any of those three and the gap is enormous.
GSP enjoys a speed advantage over most of his opponents as well so I don't see how that is even relevant outside of Edgar who is the only one of the three who isn't huge for his weight class and would still be very fast for a FW. They are all naturally superior athletes that wouldn't magically disappear if they happened to grow a few more inches. If Cruz were 6'1" and fighting at MW he would have elite speed for a MW. These aren't guys who are fast because they weigh less they have elite quickness compared with fighters of the same size.
