who has Cain fought so far? Just a bunch of irrelevant guys if you ask me..
Overeem has been in there against the elite, even as a kid.
Most of the guys he fought and got KOed were the most feared MMA strikers of the time.
Not to mention Overeems stand up is >>>>>>>>>>>> than it was then.
Cain's striking has also improved leaps and bounds from his Kongo fight, but Overeem is KOing K1 fighters, Cain is KOing Zombie Nog.
