Based on what I saw from Spence Jr. from his recent fight, the phase of the rounds are a bit slow, I hope he can keep up with Pacquiao's pacing since Pacquiao won't slow down from beginning to end so if ever Spence won this fight with a knock out he will be the next superstar of boxing.
This is what I observed, he seems slow on his previous fight unlike an aged pacman on hist last fight. I see that he's good in body shots and most of his fight ends up with a powerful body shots with a slow opponent but against a fast, strong puches and experienced fighter such pacman it's a different fight from his previous fights. Well, lets see if we still see a fast and powerful pacman and improved Spence.
