Pacquaio and his camp maintains that 8 weeks is all thats needed for Pacman to get into optimum shape and readiness for a fight. However, for Floyd, it seems to me that Pacquaio would not need more conditioning work but more skill work, so maybe an extra week of working on the skills portion would be ideal? To work on cutting off the ring, getting the left hand in on Floyd's shell defense, bodywork with the right hook and parrying the jab and working the counter jab would be my armchair quarterback's view on getting Pacquaio ready for Floyd.
Well roach is more of an expert than me but i think he would need more than 8 weeks, sure they could get him in optical fighting shape but i agree with the OP, they need to do some skills work. Mainly that should be based on pac tightening his defence and working on getting inside on a fighter who can match his speed, is more accurate and has a significant reach advantage
I think that Manny has the advantage over other fighters in training that he doesn't need to worry about making weight. He can focus entirley on conditioning and skills training so maybe that's why he only needs 8 weeks.
