People are super ignorant if they think conor is anywhere near 160lbs right now, His coach is on record saying he was walking around at 177lbs while fighting at featherweight.
Does this look like a 15lb weight cut to you? if he was cutting from 160 to 145 5+ years ago for featherweight that would be just a 15lb cut, you are deluded if you think a 15lb weight cut results in this.
Example 1: This is what an 18lb weight cut looks like, marcos madiana re-hydrated 18lbs after weighing in at 147lbs vs mayweather, compare how he look son the scale compared to conor

Example 2
Victor ortiz re-hydrated 17lbs after weighing in at 147lbs vs mayweather, this is what a 17lb weight cut looks like
Chael sonnen said conor told him that he was 172lbs just 8 days out for his fight with chad mendes at 145lbs, 8 day's out he was already killing himself making weight just look at the state of him, the guy was cutting 30+lbs for feather weight, he is WAY bigger now than he was back then,
