There are a lot of users from the Philippines here and obviously they are going to support their national hero. On the other hand, Conor McGregor hails from Ireland and his fans are not that visible. 4-5 years ago, Pacquiao was in his prime form and any match against McGregor would have been a cakewalk for him. But those days are long gone, and now he is hardly active in boxing.
Got some point. Pacquiao is no longer on his prime and age gap also have factor from this possible fight,
McGregor already went inside the ring fighting against Mayweather.
Though the chance is really slim for him to win against Mayweathr but the fight take place collecting money
from the fans from both boxing and MMA.
For the same reason, this fight may take place as boxing is a business. Promoters are willing to pushed this once interest from the fans
shows numbers, exhibition is for collecting paycheck both fighters are most interested with how much they will be banking after this fight.
