Martinez is the only fighter I feel confident will give Manny Pacquiao the most problems. Floyd can probably beat Pacquiao but Sergio's style would be more effective and more of a threat to Pacquiao. Plus you know that would be a fight because Sergio would never back up and run away.
Dibella typed on Twitter saturday that he could make Pac/Martinez @ 154 with Martinez weighing only 165 on fight night.

I much like this fight now than Marquez, Bradley, Ortiz... Pacquiao has nothing to prove at Welterweight he already dominated this divisions. It's time to take a much riskier opponent. Martinez is the best choice for Pacquiao.
