Yes, Julio can punch and Kirkland's chin has been suspect. But, he showed that he can get up after being hit hard as f**k by Angulo, who's as big a puncher as Julio, and come back.
Chavez has faced no one near the punching power that Kirkland has, and James has good stamina with Wolfe. I got Kirkland.
Anne Wolfe could do everything to make Kirkland the strongest, fastest, most energetic boxer out there, but there is something she cannot do and that's fix kirkland's chin. I have to say Jr. by KO.
Chavez jr...........he's massive and can take a punch
He's massive because he loses so much weight its unhealthy. And he has yet to face a puncher anywhere near kirkland. Does Zbik's 1000 ounches count?
