The more I watch Manhoef, the more I think Silva would decimate him. Don't get me wrong at all, Melvin is awesome, but hes a technical brawler with serious power. He leaves him self open for counters. His TDD and ground game are very poor.
He has a bad habit, of never moving backwards. Now for an aggressive fighter this is great. But when you're fighting a guy like Anderson. You want lateral movement and not to just wild engages. You have to create your openings. Manhoef will not do that. He comes forward guns blazing. His cardio has always been a bit of a question mark as well.
The other fighters who share the same philosophy as Manhoef, (though I must admit not to the same extent he does) are. Griffin/Leben/Irvin and Rich Franklin and Hendo (to a lesser degree) All of them got dealt with very quickly. I see Manhoef vs Silva being probably one of the best examples of counter-striking you're ever likely to see.
All that said, I do love watching Manhoef and I really respect his attitude and reason for why he fights. He's a sick dude!
I probably was being sarcastic in the above post. I think you should flame me for it.
