Cotto used to absolutely murder himself to get to 140lbs, in the ring he would be 160lbs or maybe more. When you look at that weight hike, it's quite similar for Wright to get to 147. It would also be murder for Oscar to get to 147lbs, so they'd both be in equally bad shape in the ring to get down there though. If Winky's in the ring weight is 170lbs, it would be possible to get down to 147lbs, but he'd look like a chemo patient on the scale.
