Hernandez who has background in Muay Thai and wrestling can have longer endurance with more guaranteed power performance, but I predict Michel Pereira can win by KO even though in the end it all ended with an unexpected surprise where Hernandez got the win by KO.
This was really unexpected and Michel Pereira had to accept defeat after series of wins that he had achieved.
You are right that Hernandez was not playing around and he was on top of Pereira with some pretty hard elbows to the face causing the fight to be stopped it was an embarrassing defeat for Pereira.
