Liddell would win this one. As great as Silva is and as precise a striker he is, Chuck has a knack for counter punching at the right angle at the right time and hittin the button everytime. We all know Chuck probably hits harder or as hard as anyone. He has that 1 punch fight changer. Lets not forget Liddell is a world class kickboxer himself. It would start kind of slow because both would be cautious of the others striking ability. Id say Liddell 3rd round KO.
