I think the strategy that they used with Oscar dela Hoya will work a bit... turning JMM constantly and sneaking in the left whilst ducking and moving away.. as all observers noticed Pacquiao must do away with the pump jab instead try more of the straight left before Marquez could step back... Marquez always steps back after the pump fake and jab to counter the straight left of Manny.
Strength training for the left for more devastating power when it lands as we all saw the power in Manny's left could be developed more and the right hook also.. and more core training because the body is all that's gonna be left for Marquez to take if he fights smart and not brawl.
The problem might be is if Pac thinks his left is more powerful
, he might overuse it.
He could have snap left lead Juan's face all night after he busted his
nose and watch Juan bleed to death.
Instead he wanted to throw his haymaker left one too many times.
Pac did not remember it was his short left that missed then
the right hook busted his noses.
He was able to do that because he had the right angle and distance.
Pac just has low ring IQ I think.
