Tyson was a bad bad person, but I dont think Lennox Lewis gets enough respect. I know its odd to just bring him up randomly, and he didnt have the highlight reel Tyson had, but that dude was a fucking terror. Beat every dude he faced, most by brutal KO, and the only thing you can fault him for is a questionable chin, which Tyson also had.
Anyway, Im shocked that Dos Santos got tooled so easily. I think its more of a testament to MMA and how tough it is to consistently win fights no matter who you are. A big thing that matters is a fighters condition leading up to the fight. By all accounts Cain wasnt right before the first fight, and sometimes thats bullshit, but in his situation it seems to be legit. But Dos Santos was supposed to be 100% going into this fight so who knows? All I know is I need to see a 3rd fight between them. Yeah I want to see Velasquez Overeem (as that is an MMA purists dream, pure, savage striking vs hybrid wrestler with historic takedown accuracy) but seeing Cigano fight him one more time is probably going to happen at some point.
