If none of them cut, then they fight where they are at. Cutting 5-10lbs? Not a big deal. Cutting 20 or more lbs and I believe the "kitty" is the only word to describe these guys. If Khabib and Ferguson fight at 155lbs, then YES, they are a couple of chickenshit 200lb guys fighting for the 155lb title. It's like a highschooler trying to fail an aptitude test so that he can compete against elementary school students in a spelling "bee".
Like I said, the HW's and BJ Penn seem to be the only guys that are true warriors.
Now, some punk will come along and say that some HWs cut to make the 265lb limit but there isn't SuperHeavyweight Division.
