i assume that youre talking about the old version of pac? how about the current version? what will be your game plan? btw, being undefeated doesnt necessarily mean that you're unbeatable.
The best way to beat Calzaghe is switch tactics throughout the fight. Start by drawing him into a toe to toe battle (as Kessler did) then fight on the retreat. Joe is awfully sloppy when he has to chase someone..... he is much better when he can fight aggressively on the back foot (see Kessler again).
Manny Pac? Box him at distance ala JMM Floyd Mayweather? - Take him into a war IF you can catch him Chad Dawson? - Fast speed, high volume of punches Kelly Pavlik? Simply out-box. Miguel Cotto? Frustrate him by clinching when you can and staying at distance when you can't. Bernard Hopkins? Take him into a war. Paul Williams? - Stay up close and personal with him. Shane Mosley? - Loaded gloves! (Not really) I think it all depends on how Mosley perfoms. Arthur Abraham? Pressure fighting.
take a gun+bullets. Fire. Point at Referee and judges - demand they make the post fight/winner announcements. Simple.
Pacman - Pretty much size him up and force him into a closed space, Pac likes to go in all guns blazing then use his speed to avoid being hit Dawson - A highwork rate and good footwork, he got away with johnson but someone like calzaghe would tko/ud him Pavlik - Counter punching and side stepping or a high workrate to pressure him Mayweather - Bring the fight to him, relentless aggression. unfortunatly hattons chin went a bit wobbly and his head went into the ring post but he wobbled mayweather at times Cotto - Fill your gloves with plaster Hopkins - Keep attacking and be aggressive but be aware of his counterpunch Williams - Havent seen him fight so dunno Mosley - mixture of speed and footwork, he leaves his sides wide open so hes not hard to hit if your crafty like cotto Abraham - Havent seen him fight so dunno Calzaghe - He has many different styles so the only way to beat him is to adapt constantly and get in close. Calzaghe works best at distance and defensively. make joe bring the fight to you and wait to get a counterpunch in
