New York - For veteran trainer Andre Rozier, he may be in the corner of the biggest fight he’s ever worked when his longtime pupil Daniel Jacobs (32-1, 29 KOs) takes on IBO, IBF, WBA, WBC middleweight champion, Gennady ‘GGG” Golovkin (36-0, 33 KO’s) in the main event of an HBO Pay-Per-View card.

The fight takes place this coming Saturday night at Madison Square Garden in New York City.

Although he’s preparing for a second crack at Golovkin, he did reflect on the recent knockout of his nephew, Curtis Stevens, who this past Saturday night was knocked unconscious in the third round of his fight with David Lemieux.

Three fights ago, Stevens decided to switch trainers by leaving Rozier and hiring known coach John David Jackson, who is currently best known for his work with Sergey Kovalev.

Rozier saw a difference in the fighter he once trained.

“He did what he’s alway done before,” Rozier told BoxingScene.com. “He was complacent and laying on the ropes. But unlike other times, his defense was was faltering. Usually he throws a left hook, he often puts up his right hand to block the shot. This time he didn’t and he paid for it.”

One could only imagine how hard it was for Rozier to watch his nephew remain motionless on the canvas, but the trainer believes Stevens has the right tools to win the fight but didn’t put them to use.

“He really didn’t utilize his jab enough,” explained Rozier. “He went to the body once or twice. He honestly should have jabbed, hooked, went to the body and rolled to the right with everything. He was in the same place all the time and he paid for it.”

Rozier strongly feels that if Stevens was still under his watch, then those tools would have been used properly.

“If he was working under my tutelage - we would have worked on staying in the middle of the ring. I would have had him rolling hooks, working the body, and his jab would have been working all night long, and counters with right hands,” Rozier said.

Rozier will use the mistakes the Stevens made in last week’s fight, and during his TKO loss against Golovkin in 2013, in the upcoming fight with GGG.

“You can always apply mistakes into another fight. You take a mistake and you put it into the memory bank. You don’t lay on the rope and wait for something to happen. We’re going to learn from others' mistakes and try your best not to learn from your own," Rozier said.
