It's funny that people keep talking about the size difference...uhhh, anybody remember Bendo vs Edgar? Two very close fights with Bendo having a huge size advantage. Aldo is not small. If/when he moves up to lightweight he will bring size and strength. Look at his shoulders. He is not a slight man. He will pack on quality muscle without having to cut so drastically. I think he will be scary at lightweight and will continue his legacy there. I like Ben Henderson, but he definitely is not on the same level as Aldo...few are.
