UFC 191 headliner and reigning flyweight champion Demetrious Johnson is going against the grain as far as the idea that Cris Cyborg must drop to 135 lbs to face Ronda Rousey. In a media event held in Los Angeles on Monday, Johnson said that Cyborg is simply too big to fight at 135: (Via MMA Fighting)
"The Cyborg and Ronda Rousey fight, Ronda is like, 'I'll fight you at 135,' Johnson said. "If [Cyborg] made 135, and granted, she did the drugs and that's in the past and she's a big woman from doing that, but her making 135 pounds, it wouldn't be the same Cris Cyborg as at 145."
UFC president Dana White and Ronda Rousey have both made it clear that for Cyborg to get the superfight, the current Invicta FC featherweight champion must cut to 135 pounds for the first time in her career. After she wins one fight at 135, then she'd get her crack at Rousey. All that said, Johnson doesn't have much interest in this fight being at 135, and called it "garbage":
"When people get pumped up at the fight, i can't get pumped up," Johnson said. "Because it's not going to be the same Cris Cyborg at 145 that's going to be all drained, especially without an IV, to me, that's garbage."
As garbage a proposition as it seems to him, it's the direction that the UFC is probably not willing to budge on. No 140 catchweight, no Rousey to 145, none of that. It's Cyborg at 135 or bust, and the onus is on her to considerably change her frame to make bantamweight.
