Rampage has been finished 5 times in 50 fights, most of which were spent fighting against the best of the absolute best over ten years. Even in those finishes, he showed how tough he was. He fought with broken ribs against Rua when Rua was at his most roided and dangerous, and was basically a walking punching bag for a few minutes until the ref had to step in. He ate 50 knees against Wanderlei and was so beat up he was tipped over by the ref intervening to save his life, but he never quit the entire time. He had to legit be put to sleep in one of the most vicious ways I've ever seen in the second Wanderlei fight. His two submission losses are when he was super green against one of the P4P GOAT's, and after fending off the roided P4P GOAT's takedowns for three rounds.
Everyone else he's beaten or simply been overwhelmed with top grappling by. Even in those fights like against Rashad, he was lighting him up at the end and probably would have KO'd him in the 'championship rounds'. He fought back, he didn't break.
I agree his game off of his back has no offence and little defence, and that's why he's lost more fights than he should have. But that's due to a lack of skill, not mental weakness. I think that's ridiculous to say, because Rampage would be on my list of toughest guys in the history of the sport.
Compare that to Chael's record of quitting any time a strong man puts him on his back, or how he reacts to getting hit on the feet and being out of range for a takedown, and it's not even close. fake edit: ffs Chael has literally been finished in 14 of his 15 losses, I just checked. I didn't realize it was that bad lirl that's a guy who wilts when he can't impose his will. He's been finished in a third of his professional fights, and looking at his record it's consistent from the beginning of his career.
Chael might get a takedown in this fight, he might win a boring decision if those muscles are all show and no go. It's hard to predict these old dawg fights, but I think Rampage is roided and in decent shape, and is less broken down than Chael. Who knows, but to put it another way, anyone who tells you prime Rampage doesn't murder prime Chael probably posts on The_Donald.
