No, but combine that with the fact that Silva had a cracked rib and wanted to prove a point by beating Sonnen with BJJ, and you get what idiot fight fans think is the closest thing to a challenge for Anderson Silva. Sonnen is not that good of a fighter, if he was any good at all he would have been able to land one of the thousand or so shots he tried to take at Anderson while he was on top of him. Like most Silva opponents, he got frustrated with the fact he could not strike cleaning, so he resorted to playing patty cake on Silva's face. Look what that got him, 23 minutes of top position and a tap out, thanks for coming.
After seeing what Silva did to Belfort, do you really think he could not have made a similar striking move on Sonnen? He chose not to. I don't get why people hate Silva so much, like I said before, you cannot blame him alone for some boring fights, there was another fighter in that octagon that decided not to engage Anderson, and if you don't like how he danced around the ring, I consider that a slight on the other fighter, who when given a golden opportunity to take a shot at the champ, does not jump on it.
What cracks me up is people who think Sonnen, or any other wrestler for that matter, pose a problem to Silva. He has only submitted some of the best wrestlers and BJJ guys in MMA like Henderson, Lutter and Sonnen. When you beat the best at their own game, then I think that usually means you are better than them. I only see 2 guys who might stand a chance of beating Silva: Jon Jones and he still needs some time to improve or Alistair Overeem if he ever came back down to LHW. Jones needs at least 4 more fights or 2 years of training before he can even think of stepping into the ring with Anderson, and Overeem is just as much of a freak as Anderson, but due to weight and contracts, this one probably will never happen.
