we must be looking at different pics. nassers back certainly doesnt lack thickness or width..yes his back isnt as good as dorians but certainly not as bad as you and many others make it out to be.
also in second pic dorian is standing closer to the camera.
and in pic with ray-dorian-nasser you can see that nassers back is plenty wide
in top pic you are comparing him to ronnie who has one of the best backs of all time. so having a back that isnt as good as ronnie doesnt necessarily say that much. you have to look at the big picture.
Again you're missing the point , his back isn't obviously as good as Dorian's or Ronnies however his back isn't the back of a 285 pound bodybuilder in terms of width , thickness forget detail.
Mind you Ronnie Coleman is 249 pounds in that picture Nasser is at the least 25 pounds heavier in that pic and you'd never know it. The second pic is Dorian at 257 pounds and Nasser is at least 275 and his back doesn't look as wide or as thick
Third & forth pic both are 270 pounds and Dorian's back is noticeably wider and thickness is unmatched .
Nasser's back was a major liability and the Flex critique is accurate , from the back ( especially the double biceps ) Nasser does look a narrow and thin
