I know what you mean Lacy, I think fighters that have never been sparked out cold tend to be the ones that have long careers, Hopkins, Winky, Mayweather, Vitali Klitschko, their bodies will wear out due to injuries long before people whink "Oh my god there's no way this guy should carry on". Fighters like Holyfield, Morales, Kevin Kelly and many others at the minute, your watching from behind the sofa these days because they've faded so badly and have taking too many beatings.
