I you are looking for a good fight then Conor needs to fight someone who is coming up in the sport of boxing and not someone who is established and at the top of the game. I am sure Manny will school him and if Conor wants his stock to rise in boxing he needs a win and not starting a career with two losses.
There is a difference in approach between Manny Pacquiao and Floyd Mayweather, Manny is aggressive in his approach and Conor McGregor is a really good counter puncher and the problem he had with Mayweather is that he was not able to find the trigger as he was looking for that counter punch and he never got that and then he gassed out. So it will be an interesting fight if it happens as i still believe style makes fight.
Mcgregor is not a boxer but Im sure he learned a lot from his fight before to Mayweather and hopefully this will be a good fight if ever because Manny is a real one and he wont end the game without a fight. Though Im still thinking about a fight for money just like before since Manny is a great boxer well this fight should be more serious for Manny considering his Age.
The bottomline of course of this match is about the money. But yes it is true, McGregor and Pacquiao will give a better fight in the ring as they will really give what they've got. Unlike Mayweather, which is always playing safe, counting technicals and others. And if this will happen, I think boxing fans will still watch this fight with enthusiasm.
