This is a known side by side comparison shot of both in the exact same pose
Now since you can't lengthen muscles , Ronnie will NEVER have bigger traps than Dorian no matter how much weight he puts on , now also consider Dorian's traps are separated at the upper & lower ( Ronnie's aren't ) and you can see striations in Dorians , you can't in Ronnie's , thickness? another advantage for Dorian , while Ronnie's traps may have been as thick as Dorians when he was at his heaviest however what does that mean when it's at the extent of density , Dorian's lack NOTHING , visually traps in a clear advantage for Dorian
Teres & infraspinatus , just take a look at the picture , look at the sheer size differential between the two , look at the depth of Dorians VS Ronnie's , Ronnie's look compressed compared to Dorian , and the development is crystal clear on Dorian , another clear advantage for Dorian
Lats , Dorian's insert lower near the waist , already a clear cut advantage for Dorian , again you can't improve on this at all , it's akin to have high calves VS low ones. now you tell me which is more desirable? Dorian's lats occupy more space between his arms than Ronnie's , and they're are littered with deeply etched striations the whole length of his lats , one area Ronnie may have equaled or surpassed Yates is lat width , and this debatable , if he was just as wide or wider it would have been at the expense of density so he gains nothing when all things are considered , another clear advantage for Dorian
Spinal erectors , Yates again his x-mass tree was much sharper
There is honestly now where I see Ronnie beating Dorian in the back department regardless of what Team Flex dictates this year ( they had Yates the clear cut winner in 2000 , Ronnie back go wider & ' thicker ' at the expense of density )
