This could mark the end of the heavyweight division as we know it.
World champion Lennox Lewis will dismantle No. 1 contender David Tua Saturday
night in Las Vegas. And, if previous warnings hold true, such a result --
whether it's an early devastating knockout or a prolonged pummeling -- will
wipe out the old heavyweight guard, leaving a group of unproven youngsters to
tussle over championship belts that will become even more irrelevant than
they already are.
