Pacquaio would have beaten Morales and Barrera even in their primes. Pacquaio's punches are really heavier than the two. Somebody may rebutt that it's not about strength alone (its about skills, speed, etc.unfortunately pacquaio has all those).... but you must agree with me guys that Pacquaio has a lot more strength and power in his punches than Morales and Barrera.
