You are an idiot. You don't ever know the definition of pound for pound. We can't shrink or make bigger fighters and pretend how they would do. At different weights you need different athletic abilities. A straweight doesn't fight like a heavyweight. It's easy to say that Ivan Calderon would dance circles around Lennox Lewis who was a flat headshooter or whatever if we put them at the same size, but it's not realistic, we can't "imagine" that.
