The stamina still there for Pacguiao and that's good with his age.
We really can't tell what will happened to this fight, but I'm also curious if Pacquiao will stand still as this new possible opponent of him' really have that strength to knock him down if he put he's guard down, but again, both side do the same power and skills it will depend
in how the fight turned.
He is still training hard and the ageing hasn't affected his agility or strength, as seen from the match against Thurman. However, if the fight against Terence Crawford actually goes ahead, then Pacquiao may be facing a much tougher opponent. I will be quite interested to know how the sportsbooks place their odds for both the athletes. The betting is going to be heavily biased in favor of Pacquiao (a lot more people will bet in favor of Pacquaio when compared to the same for Crawford).
