McGregor wanted this fight. That just means that he is aware of the match being unfair which supports the fact that he is not just after this fight but after the fact that this match will generate millions and millions of money. In terms of retirement, I don't think this will be his last one. There are a lot of times that people are talking about retirement but Manny is just looking at what he can do as long as he's still kicking.
There will be a mismatch given that they are from different leagues. This ain't street fight wherein a player would only consider skills. Rules, capabilities and kind of training would matter. But as I've said, I doubt any of this player would aim for the victory, they know to themselves the gap between each of them. This is more of a 'celebrity fight', hoping you guys are already getting my point. Won't make a speculation on who will be victorious, but will rather enjoy the fight.
Considering the mismatch, we all know how will the match go but as you've said, speculation seems to be interesting since with the aging Manny Pacquiao doesn't have that many fights in the past unlike McGregor still active on the octagon. I am more interested in seeing how Manny Pacquiao changed his style from his last fight.
