Chavez is fat, slow, lazy, has no heart and zero ring IQ. He is a tough ******* though and has good punhes. Froch just pounds on the fat lummox who eats punches all night with Carl's chin absorbing any of Chavez Jr's own until the ref stops in round 10 or 11.
Froch would beat him convincingly. Chavez would come right at him which is not going to work with Froch. He'll soak up anything Chavez can dish out and grind him down and stop him around the 10th round. Froch boxes behind his long jab and when Chavez Jr does get close he fires right back and out works Chavez Jr.
froch walks through Chavez as long as he don't underestimate him. He will look bad in a few rounds soaking it up, but aftert that the end wont be long.
