"It's OK, as long as we get the work done," he said.
Lampley, who will call Saturday's fight, said Chavez has improved greatly since inviting Roach into his corner.
"He has a far greater sense of where to be and when to be somewhere in the ring," Lampley said. "He moves with much greater fluidity. He can set things up. He used to just walk in and fire punches. Now he does more to set up his punches, particularly the left hook to the body."
Just like his old man.
Roach admitted he's had work to do with the young prospect.
"He has the instincts of a fighter; he's just not a natural fighter like his father was," Roach said.
It is certain that Martinez, who came to the sport very late at age 20, doesn't think Chavez is the fighter his father was.
During a dual interview with boxing analyst Max Kellerman, Martinez glared at Chavez and said, "You're living in a delusion, based on your legendary father. When are you going to stop believing that?"
To which Chavez retorted, "I will never stop being my father's son."
But for Chavez to stop being just a son of legend and start on the path to becoming a legend himself, he'll have to beat Martinez on Saturday.
