On the underlined part, above:
Not really. Pacquiao weighed at his heaviest vs. Clottey when he was 145 3/4 and took the scale for a Jr. Middleweight catchweight limit of 151 lbs. while weighing a mere 144.5.
The Martinez-PWilliams rematch had a catchweight limit of 158 lbs. Sergio came unto the scale at three quarters of a pound less.
Thus, while Sergio only has to go down 3 to 4 lbs. (he was 159 or more in Martinez-Williams I and vs. Pavlik), Pacquiao shall have to put on around 10 lbs.
Note: Martinez only has a 50% stoppage rate in his entire career (25 KO's in 50 fights), with 21 of those accomplished when fighting north of 150 lbs.
