Small, fast, explosive, skilled, champion

BadMon -I LOVE GSP - actually Cain seems like a nice guy.
Tyson was nice when he was young. then he was worth about 300 million.
Cain will be humble with his 400K pay days for a while. he can't buy tigers.
I'd say he's nice now, he was a maniac when he was younger. just a disgraceful human being.
good to see he's changed.

No one works the body with combos like Tyson, no one.
TJ Grant looked the most like Tyson tonight, haha. :)

Care to elaborate? 
It's a "Hangover" quote.
Lol @ Cain being anything like Tyson!! LMFAO!!
You've clearly never studied the sweet science.
Lololololololooo!!!
Unseen -My brother did a interview with him, said Cain was the biggest stone faced guy ever.I LOVE GSP - actually Cain seems like a nice guy."I thought he was mean"
CLINTK9 - Fedor
Brown Fedor since, well he's got Brown Pride.
CLINTK9 - Fedor
This. Biggest difference is Tyson looked intimidating. Fedor looked meek, but that's what made him so beloved. When Fedor would stare down someone who looked 10x scarier than him, it was a forecast for their inevitable demise to the cyborg.
Fedor and Cain are very similar IMO. So yeah, I can see an argument for Fedor. He was small, quick, powerful, skilled and explosive as well.
And no, I'm not comparing their boxing skills. Everyone knows Tyson smokes Cain in boxing. I'm comparing them within their own sport. Can is incredibly skilled in MMA overall.
