Peter that fougth mike tyson (we get a time machine..bull him right out before he walks to the ring) versus say, the Pac who fought Cotto.
McNeeley outboxes him for 11 rounds with his superior skill and speed, before Pacquiao's strength slows Peter down and Manny lands a big haymaker for the win in the final round.
If Walker could fight Sharkey, I don't see why this can't happen. But Pacquiao almost certainly gets wrapped in a cocoon of horror.
Pacquiao by TKO. Pacquiao vs Butterbean is a much better match-up, I have Pacquiao winning that by a 4 round unanimous decision.
