As it was long suspected, it's probable that GSP won't fight at MW anymore. Remember, he was 190lbs before the Bisping fight after the weigh-in and couldn't get back up to his walking weight of 200lbs, along with numerous health problems (probably caused by his diet). Obviously at 190lbs, he can still fight at 185lbs. But he would be fighting against guys like Rockhold, Romero, etc...Who walk at 200, sometimes even 220lbs. Do you think its realistic for him to fight at MW, or does it make sense to drop to WW considering his body is obviously damaged by going to 200lbs+ through diet alone? If he took PEDs, he could make MW. Says it in interview too. Personally, I would still love to see a Whittaker fight, but at WW.
