The only way it would make sense for Pac to fight at 140, is if he was planning to... conquer the 140 division, which he clearly isn't. Pacquiao is not going to drop weight to face anybody, let alone Marquez. If Marquez feels weight is too big, then he should take on Kahn instead. Marquez ain't stupid though, he'll take this fight at 147 and earn his pay check. 140 - 147, it doesn't matter anyway, at this point of their careers, there will be only one outcome.
i want it at 140 but first jmm should fight and beat a legit 140 pounder contender or champion. so pac going down to 140 would not be for something since he is the actual lineal champ at 140. as is the case, it doesn't matter which weight they fight since they would be almost the same weight during fight night. jmm can come in 135, 140 or 142 and both will be around 145-148 when fighting.
