Much of Garnett has been false bravado and manic 'look how crazy i am' posturing.. If he were to have played in the 'bad boys' era or in the knicks vs heat brawling type era, where rough play was permitted.. he wouldnt be the menacing KG that we know now. He would be a tough great defensive player but he would be one in a pool of many.
I would have liked to see him go all 'Your wife smells like cheerios' to Charles Oakley
