I think that Estrada loves for his opponent to stand in front of him and slug it out and really doesn't have a style that I can even acknowledge but he does have power and can hurt. As far as Berto he has some style and power. I know he's young in the game but with the old stick and move he can at least survive to beat Estrada by decision. I don't know if he can knock Estrada out because he does have a chin (I watched Kermit) put it on him and his heart kept him in the game.
Why do you say that it may be too soon for Estrada...he's been around for awhile right! I think that if Berto stays calm and not go in trying to kill and win just by knock out...just stick to the basics...(boxing) he can win.
