Allen Iverson, pound for pound best?

Kevin Durant has just posted on his Instagram account that he thinks Allen Iverson is the best pound for pound baller.

"Chuck too real. He changed the way we play ball. He changed the culture of ball. He is pound for pound the best. He paved the way. I can go on and on. But he's a legend and I'm just walking the path he created."

With other small ballers like Jerry West, Nate "Tiny" Archibald, and a 190 pounder named Michael Jordan,  I think this could be a debated topic.
