Manny at 140 IMO will not be bad off...I think it will benefit him on the weight cutting issue for sure...He just has to keep in shape not get in shape to make weight comfortably...There are guys at 140 I would say hits a lot less hard then Pacquiao...Yet not with the output or speed...People will be surprised at how easily he makes the adjustment and if for some rerason he can't well he can drop back down to his comfort zone again
