I'd favour Pac. Spence being a southpaw himself doesn't have the counter straight right that JMM or Mayweather had. He'd get beaten to the punch and swarmed, that high guard defence he often uses wouldn't help him much against Pac's combinations, he needs to create space and move which is doesn't really do.
Pac talked about how bad slow ass Margarito without the doctored wraps hurt him to the body. What would Spence do to it?
Except Morales... the only man to actually defeat a prime Pac. Something EVERYBODY seems to forget. But it happened, it's all right there on tape.
Pac UD. To quick of both door and hand, plus with his own punch power and the angles I cannot see Spence keeping with him over the full 12. Close for the 1st 6 rounds then I can see Pac pulling away down the stretch. Pac 8-4 type fight.
Pac vs current Spence you would have to favor Pac,but not a safe bet... I also dont think we have seen prime Spence yet. Spence is the natural bigger man and he is a lot better then Magarito...
Fair enough Morales via decision but he then avenged that and defeated Morales 2 times over via TKO/KO. And Morales end up retiring as a result. Please do not forget that, it all right there on tape.
