Morales slipped against MAB, if you wanna call that getting KD then go for it. But his chin was never close to being exposed before Pac.
Thats like saying watch MAB-Fana to demonstrate MAB's KO power. Of course there's gonna be occasions where his power look absolutely devastating. However, like I said, Ive seen pretty much half of Naz fights and there were MANY lesser fighters that took bombs after bombs and didnt get KO'd, he had to grind down quite a few of them as much as he took many out with 1. Morales has an elite chin and he would have taken those bombs and fought back pushing the out of balance naz back.
I honestly believe all four would have beaten Hamed. Naz never had the technical skill or the defence to compete at that level, hence the beating he got the only time he fought that standard of opposition. Of course he would have a puncher's chance, but in their primes all four are too smart to let that happen.
Well unfortunately we'll never know.... too bad Naz didn't stick around and stay in the mix. Imagine EM, MAB, JMM, Naz and Pac all fighting at the same weight, same time. WOW!!!
