He looked very 'ribby' in the weigh in, it really seems like he boils down hard to make 135, i think he needs to move up to 140 same as Khan did, im also thinking the weight has effected his performances as of recently. From digging up what i could on Prescott, it seems he STARTED as a 140 pounder anyway, he won some columbian light-welterweight titles at that weight and moved down to 135 about 4 or 5 fights before he knocked out Khan, he needs to move to 140 because i think thats where his natural weight is at, he looked a bit too ribby in the stomach if you ask me, he would be a better 140 pounder, i wonder if the weight will effect him against Mitchell? (unless he does a 'Khan' and lands flush and early like his last trip to the U.K). Im not sure at all which way Mitchell VS Prescott is going, i really dont, but both outcomes will be good, if Prescott wins, theres a GOOD chance of a Khan-Prescott rematch. If Mitchell wins, then obviously a possible chance at a world title.
Not killing himself as such, but its a bit like Khans situation, he'd simply be ALOT more natural at 140, he probably has to put that extra effort into grinding down the 5 extra pounds, i just believe its the same situation as Khan. Prescott would simply be more natural, healthy and probably better at 140.
Judging by his last performance at 140 it didnt seem to help Prescott moving up, he looked very lethargic against Vazquez. I really have no idea whatsoever how this fight is gonna go, really overshadows the main event IMO
