What mistake did Chael make? That spinning back fist is a move he practices do a youtube search on his hook kick back fist combo. Silva ducked it and he fell, there is no mistake it just got counter well. How many fighters not named ANderson Silva would have timed that and ducked it?
Why was it domination? Chael got stuff on 3 take down attempts, and got finished. SIlva dropped him with a right hand, and GNP him. The only difference is Chael was attacking when past opponents would freeze up. Name me one time where Chael has been TKO?
Look at the so call mistake? Is it a mistake on Chael's part or attribution to Silva's skills? Realistically Chael saw a man with his hands down and tried to hit him, but SIlva used his legendary head movement and got him like okami,forrest,franklin,etc.
