It will also prove that the old generation of boxers is better than the current generation. It's a legend versus a champion at his peak, it's a big challenge for Spence as he will be facing the legendary in sports of boxing, and he has to win to gain more respect from the fans, but he should fight a clean fight.
This is true even though Pacquiao has the experience advantage Spence Jr. is hungry for a fight, I've seen Pacquiao dominates regardless if its a lose how he moves and the speed is fascinating and based on what I saw from Spence Jr. 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. If ever Spence won this fight with a knock out he will be the next superstar of boxing.
