Doesn't matter if Silva has 1 punch KO power. Because Anderson isn't hitting you with just 1 punch.
I would think people wish he had Chuck Liddell power so it could be over faster, but nope instead he punches you 5 times, kicks you in the face then clinches you an knees you 8 times.
He hits you with everything, if you think you can withstand his punches, well fuck go ahead stand in front of him. But its not the punches you need to watch out for, its the knees and kicks and elbows that follow within seconds.
I defiantly am not counting Irvin out because he has good power an decent striking and isn't scared to take a risk. But if he thinks he can just go stand in front of Anderson with no worries then fuck it will be a short night.
