I hate to say it but the title of this thread should be;

Holyfield: I will retire as a vegetable

And I am being serious too. Floyd Patterson, 15 years ago, spoke fluently, seemed to have all his senses and then wham, he was out of it. And he took some beatings (though some were mighty quick ones) but not the kind Holyfield has been taking. I know Floyd got knocked totally out where as I don't think Evander has been rendered totally unconscious but that means he has been taking even more blows to the head. Can we say Ali?
