He beat JDS gassing him out though so I don’t think you can say he matches Cain’s cardio. Brock has only gone the distance 2 times and they were 3 rounders bro I don’t think the proof is there for that case either. I’ll agree Nogueira, Couture, maybe Arlovski And Kharitonov but even then it’s rare and they didnt have better cardio just cardio to match I’d say that’s pretty rare.Cardio to match:
Nogueira. Maybe not speed, but cardio.
Couture.
Somebody massively undermentioned; Brock. Huge gas tank.
Of course, Fedor.
Arlovski.
JDS. Again, not speed, but cardio.
A bunch of the pre modern era HWs. 10+ minutes of straight fighting.
Kharitonov. (watch him vs Nogueira).
It may well be that during that actual time of him holding the belt, that it was hard to find cardio machines in the UFC during that year but they weren't rare.
JDS resume is better no contest but after the beating he took vs cain he became a different fighter
who is in your AVAs a member of Sherdogs Mount Rushmore of most overrated fighters of all time.
