I have never seen a boxer who becomes stronger and stronger on the later rounds. Manny has this qualities that his punches became stronger even in the later round and his stamina is just extraordinary. Those were during his prime of course.
Magsayo on the other is a good boxer but not as close as good as Manny.
Aside from speed, and punching power, Manny's reflexes are great, if you look at his
slow motion video against Mayweather, you can see how he blocked/evaded most of Floyd's punches. Aside from that, his punches come from lots of angles even with his opponent covering up, he can manage to make his punches passes those defenses and connect because of how he angles his punches. And Magsayo is very far from doing that.
Rey Vargas mostly had the physical advantage
I disagree, I think Magsayo being the heavier boxer has the physical advantage. Vargas has the reach advantage
I guess the younger Magsayo even though without any physical advantage
As for Mark Magsayo and Rey Vargas, I can say that with each fight they gain experience and it is possible that over time, one of them will become known as Manny Pacquiao.
I highly disagree, Vargas at his age is about to retire in about 5 to 6 years gaining 5 titles in 5 higher divisions within that span of time is highly impossible. Magsayo on the other hand even with his young age, considering the weight division:
minimumweight, 105 pounds (48 kg)
light flyweight, 108 pounds (49 kg)
flyweight, 112 pounds (51 kg)
super flyweight, 115 pounds (52 kg)
bantamweight, 118 pounds (53.5 kg)
super bantamweight, 122 pounds (55 kg)
featherweight, 126 pounds (57 kg) Magsayo's current weight divisionsuper featherweight, 130 pounds (59 kg)
lightweight, 135 pounds (61 kg)
super lightweight, 140 pounds (63.5 kg)
welterweight, 147 pounds (67 kg)
super welterweight, 154 pounds (70 kg)
middleweight, 160 pounds (72.5 kg)
super middleweight, 168 pounds (76 kg)
light heavyweight, 175 pounds (79 kg)
cruiserweight, 200 pounds (91 kg)
heavyweight, unlimited
