You said Old Nog, we can say that about JDS most wins.
Werdum only had a ground when they fought.
Struve, did you really put him on his record. Kongo was a better win.
Nelson isn't that good of a win, almost everyone beats him
Carwin, ok
Mir was in the worst shape when they fought.
Miocic, ok
I'd say that beating Lesnar, the same Bigfoot that wrecked Fedor and had a great fight with Hunt twice, JDS in a not close fight, Rothwell, Nog who got the belt a few fights before, and of course, as a fighter when you can't really compare these 2 because Cain is so much better, makes him better.
