Labrada wasnt as sharp anymore, difficult to compete against monsters such as Clairmonte, Francois, Levrone, Yates, Nasser, that had top conditioning as well, whilst he was a smaller guy with great shape, but couldnt realistically beat them if they were "on".
Its good he hung it up whilst at the top. Instead of dragging it out ala Bannout, Nasser, Gaspari, etc
