Juan Manuel Marquez first established himself on the world stage as a crafty counterpuncher, a style in which he is still proficient. But the first bout with Manny Pacquiao brought out the fierce warrior, able to go blood-and-guts if needed. It's a style that Marquez has embraced to enhance his counterpunching style, rather than abandon it.
Pacquiao occasionally accuses Marquez of "running" from him, the counterpunching style being Marquez's undoing in the eyes of the judges.
But, as explained in the above video of Teddy Atlas breaking down Marquez's style, counterpunching is an effective weapon that seems to be something that Pacquiao has a lot of trouble with.
Freddie Roach, Pacquiao's trainer, and others talked about it in a recent ESPN article:
"Well, Manny really loves when people come to him," [Freddie Roach] said. "He's basically a counterpuncher himself. He makes them reach for him and he counters over the top a lot. Marquez is a pure counterpuncher and doesn't come forward too often. He's always fighting off the back foot and looking for the counter. And Manny doesn't do so well with that style, because he has to be the aggressor and he's a little bit out of his comfort zone."
Former two-time heavyweight titlist Chris Byrd, who now interviews boxers and breaks down fights for his online show "The Byrd's Eye View," notes additionally that Marquez, having experienced the power of Pacquiao's left hand at the very beginning of their rivalry, is focused like a laser beam on trying to negate its impact.
"You'll notice Marquez is cutting Manny in half a lot," Byrd said. "He's staying outside the jab hand. He's staying patient. And while Pacquiao is moving, especially while he's moving all over the place, Marquez is constantly moving to his left, staying outside that jab hand. So now Pacquiao is reaching with his left hand."
For Marquez, it's about picking his spots to engage. He can counterpunch, but we've seen that the Pacquiao bouts do have flurries of big punch exchanges. He can't afford to get into too many firefights with the bigger punching, stronger man.
If he can pop Pacquiao with hard counters and only engage when he wants to engage, this could be the definitive win he's been looking for. But don't look for Pacquiao to make it easy on him.
