Anderson Silva has violently beaten the majority of his opponents since coming to the UFC in 2006. He fucked up Leben in his debut, then fucked up then-champ Rich Franklin twice. Prior to last night, he'd only been in danger once and it was in large part to a broken rib he fought with (the first Sonnen fight) and even then, he still pulled a clutch win by choking him out with about 30 seconds left in the fight.
He's fought all kinds of guys with different styles and beaten them all (Dan Henderson, Demian Maia, Thales Leites, Forrest Griffin, Yushin Okami, Vitor Belfort, etc.).
He moved up in weight and made Forrest Griffin and Stephan Bonnar look like fools.
He does things nobody else can thanks to his unbelievable reflexes (despite being in his late 30s mind you) and last night, it caught up to him. No, they didn't slow down on him and he did not look old....but he finally fought a guy who wasn't scared of him and instead of getting caught up in mind games, took the fight to him and knocked him the fuck out.
Silva is the GOAT and it was poetic justice that he got KO'd based on things he's done in victories time and again. I'll never forget the fight with Okami where he had his hands down by his waist and knocked Okami on his ass with a fucking jab. A fucking jab put him down.
