I think this would be the ultimate slugfest between 2 of the divisions toughest characters. In the end, I think bodypunching by both wears both down> But, the great Walker power prevails and "The Toy Bulldog" beats the "Raging Bull" by decision. "Walker threw enough bruising, bonecrushing left hooks to the body to set his opponants ribs afire...", "if it hadn't been for the one, the thirst, the other, the hook, might have made him the only 155 pound heavyweight champion in current boxing history...":hat
I think the most violent encounter imaginable at the weight would be Benn v Tiger. But the one you'er offering up would be...yeah.
