Well, thats a wager i would pick up if we had any chance of resolving it.

The reason being that i really dont see anyone but the monster trio having a realistic chance to defeat any of those people (and of those only Luffy and Zorro would stand a living chance against Boa Hancock )

It does also make sense storywise, with 3 people on the level of a Shichibukai Luffy's crew is a rising star, powerfull enough to be noticed by all the other major powers in the world.

If the entire crew had been that powerfull, then the Straw Hat pirates would suddenly be a candidate for a spot among the 4 emperors in the new world.
