We know Manny is a professional boxer, a legend, a champion while Conor, he's in different genre of fighting which is MMA.
That's why people believe he will win here easily against an MMA fighter.
But despite of that, he can actually win through numbers and profits of this match so that's why this is a good match for him. I've heard that this match will be for real.
That's what Conor wants, he wants to make this his 2nd professional fight after the Mayweather fight (correct me if I'm wrong).
If the fight is going to be MMA format Connor will have a big edge but if it is going to be a boxing match Pacquiao will win and even knock him out I read in one article that Mayweather did not even take the training seriously and yet he won in a loop sided match, what more if he fights Manny.
