Clearly, Pacquiao will have to win the fight based on his speed but that doesn't mean he's going to be on the run.
"I don't know if I'll do it (test Margarito's power), but it's part of the game," said Pacquiao, who worried fight fans and sent shrivers down Freddie Roach’s spine when he allowed the bigger Cotto to take clear shots during their earlier battles.
Pacman also took some big shots to the body early in his fight against Joshua Clottey. The Philippine Daily Inquirer says it was all part of the plan.
"It was part of Pacquiao's ploy. He got hurt, of course, but Pacquiao pretended the punches didn’t have any lasting effect.
But Pacquiao has a penchant for courting disaster.
Even during sparring sessions, he sometimes lets his partner bang away to gauge his toughness. Sometimes, he does it to lure his attacker to open up."

Mostly in a sparring video someone posted up a couple days ago pac just let the guy hit him without hitting him back
