Ok. Ali? Joe Louis? George Foreman? Certainly among the best of all time, although I think I'd have to give it to Foreman as the toughest and scrappiest of the bunch. He just wouldnt lay down and die. Even after........what, 13 kids? Those grills? His daughter boxing? Still looks like he could go back into training. But the best fighter overall? Lennox Lewis. He's smart, uses tactics in the ring to wear down his opponents, AND has the guns to slug it out with just about anyone toe to toe.
