If The Rahman that beat lewis in fight 1 and the Rahman that ripped Meehan to pieces then i would say Rahman..
Most importantly who cares. For the record Moorer doesnt even have a wing or a prayer.His got more holes in him than swiss cheese.
Rahman would at this point, but it could go either way. Moorer is well passed his prime and needs to retire. Moorer has no chin left. Rahman tko8 Moorer
