It wasn't where they were ,but the fact he wasn't training for his fight with Rahman... Lennox is known for not taking fights seriously. Ali never had trouble travelling, all the mexicans that have come up to the states and have done well. Monzon, Duran, The few cubans way back when, kid chocolate, kid Gavilan, Pacquaio(as was mentioned), Wright did well in Europe. Mayweather though he hasn't left the states has often been the hated boxer in his fights which resembles being the visitor, and he's done fine.
