no featherweight cuts 35lbs, that's absurd. a heavyweight, maybe. but there aren't many HWs above the 265 limit.
a 15lbs cut is pretty standard and can be done by more or less anyone, though it is far more difficult at the lower weights. i guess the more extreme cutters at the lowest classes still do it.
what people don't realize is that after a certain point, every next pound gets exponentially more difficult to lose. cutting 20lbs isn't 30% more difficult than cutting 15lbs. it's a fucking nightmare.
not to mention 90% of sherdog thinks walk around weight is fight night weight, so when they hear khabib is 200lbs when he's out of camp, they assume he cuts 45lbs. they are retarded.
