I just hope Valero doesn't get permanently damaged, considering his accident. Pac is a beast. Hopefully it is a good fight that doesn't end in tragedy with an injury like Valero has. But in any case, I doubt it will be like that. Pac has a very good chin and Valero has never fought anyone Elite, especially not on Pac's level. Pac has cracked seasoned and proven chins. Pac will box this guy and stop him more than likely. But if he brawls, it could shape up to be a war. But I don't think Valero could take it for long.
There is no reason to make this fight unless Pacquiao just really wants Valero to be another face on his career highlight reel. The only time it would really be competitve is when they touch gloves, after that, the difference between the two would become very apparent when the first round begins.
while its true pac will outclass valero, you gotta give the man credit for taking on everybody. He's the first fighter of any stature to call out the challenger with a perfect 100% KO ratio
