you can go on and on about dorian's erector spinae all you want ND, but the fact he that he has never matched this back:
it has the perfect combo of:
detail
thickness (not flat like yates)
taper
great arms
As neo mentioned, dorian's back flattens out in the rear double bi pose.
posting shot after shot of him flexing his lower back does not in any way shape or form change this.
You just type empty words Hulkster , Yates never matched this back

sure he did , Yates has one of the thickest backs in the history of bodybuilding , period end of sentence and you people are mistaking density with flatness , and just because Yates' back appears flat in the back double biceps shot doesn't mean a thing , it doesn't mean his back is any less impressive , you people are basing it on a personal preference , here is McGough on Dorian's back 1995
Flex magazine Dec 1995
Back , upper and lower , is sensational in EVERY respect : width , thickness and detail. stating the obvious and here is the criteria for the back double biceps shot
Back Double Biceps (see Figure 4)
Standing with his back to the judges, the competitor will
bend the arms and wrists as in the Front Double Biceps
pose, and will place one foot back, resting on the toes.
He will then contract the arm muscles as well as the
muscles of the shoulders, upper and lower back, thigh
and calf muscles.
The judge will first survey the arm muscles and then do
the head-to-foot survey, during which there are more
muscle groups to look at than in all of the other poses.
This includes the neck, deltoids, biceps, triceps, forearm,
trapezius, teres, infraspinatus, erector spinae, external
obliques, latissimus dorsi, gluteus, thigh biceps, and
calves. This pose, probably more than the others, will
help the judge to determine the quality of the
competitor’s muscle density, definition, and overall
balance.So try as you may to find advantages for Ronnie in the end Yates simply meets the criteria better , now you can harp on Ronnie's advantages in biceps and quads sweep but those are all silenced by the fact Dorian has the better density & balance and proportion equal if not superior definition is more complete because of calves and notice not once did they mention taper
You always insist the only advantage Yates' has is lower back and thats pure nonsense and I always posts pictures show the whole back but you always hyper focus on the lower back , at the same weight ( and even with Dorian at a weight disadvantage ) Yates has bigger thicker traps I mean this isn't really debatable
Dorian's lats are outstanding in terms of sweep ( seen much better in the latspreads ) the thickness and detail in the lower lats how they feather the whole length , and the thickness and detail in the erector spinae another clear advantage for Dorian , teres and infraspinatus are about equal in terms of detail and development but to sum this up again using the words of McGough
Flex magazine Dec 1995
Back , upper and lower , is sensational in EVERY respect : width , thickness and detail.
Dorian really does have a outstanding back in EVERY respect and from an symmetry standpoint ( a partial symmetry standpoint one from small waist & hips and smaller joints ) Dorian's back double biceps shot may not be better than Ronnies , it simply meets the criteria better than Ronnie's from the point of balance & proportion ( the other part of symmetry ) muscular bulk ( 260 pounds ) conditioning ( compared with Ronnie 2001 ASC may be a tie ) and density ( Yates all the way ) and completeness I think Dorian has a better shot , it may not be a better looking shot ( aesthetics ) but Dorian never won because he had the prettiest physique .
So please refrain from making empty statements that harp on a fraction of what the judges look for all the while ignoring the many and clear advantages of the criteria that favor Dorian.
