What made Wanderlei the fighter he was, truly was his mindset that he was invincible. It wasn't a facade. He truly wanted to hurt everybody...badly.
You could see it even against Mark Hunt and Mirko (1st fight) who were HWs. Split decision loss and a draw. After losing to Hunt, Arona it slowly faded and when the vaunted LHK came it shattered it. Hendo was the icing on the cake.
Basically how do you stop someone who has that kind of power and who you know is coming at you 100mph at full speed for all rounds. Present day Wand knows he can longer fight like that which kinda sucks for the newer fans. Him and Shogun are the last remnants of a by gone era.
Ultimately I think Wand chose this fight and at LHW to end his career to a respectable fighter whom he admires.
PS: Adding foot stomps and soccer kicks helped. Just anything that simulated an actual street fight where everything goes. That was his weapon to create organized chaos where fists, kicks, knees, then stomps came at you in all directions. It was pure savageness at its finest.
That is a state of the art description. I sure miss those times. Gotta love Wand and all his legacy.
