There's no question Anderson Silva is the most dominant Middleweight Champion of all time. This sport is still very young tho and already claiming we are witnessing the G.O.A.T is premature to say the least. This doesn't mean we can't all be amazed every time Silva steps into the cage and uses beautiful head movement and lighting quick jabs to finish his opponents. We were all in aw at Chuck Lidell knocking people out cold with one punch stepping backwards. Even tho both of these are incredible feats The G.O.A.T will have to be someone who can do more. The fighter who can hold two belts simultaneously with what is considered to be the two most staked divisions is the fighter who will be crowned the Greatest of All Time. Sorry but Anderson isn't even close.
