People need to stop pretending McG is stepping up huge here. He's a huge FW and he himself said his natural fight weight is LW and that he walks around above 170. Nate is a natural LW too. It's not like McG is taking on Rockhold or Weidman. These guys are going to be the same size
Can I just ask what the definition of "natural" weightclass is?
I would think if you walk at say 77.7kg (170) in shape at the end of your camp you are a natural Welterweight because you naturally weigh that before cutting water weight.
The way natural weightclass is Lightweight is thrown about is disconcerting since McGregor is a natural Middleweight at the moment walking above 77.7 kg by about 5kg or more.
