his posing sucks ass.
This, the posing, and the fact that Nasser was soft as a baby's ass from the back is what allowed Dorian to continue his reign that year. Nasser had him from the front, but Dorian from the back, and Dorian posed better and didn't allow his bicep or tricep tear to be focused on. He hid those flaws, and Nasser just couldn't pull it off.
