in that first pic i see, flat as a pancake back with zero taper. ripped to shreds and dry. shitty arms with biceps non-exsistent, less then stellar hams and great calves. glutes could also be harder and more striated. second pic is a stupid pic that is blown up and on a weird angle.
thrid pic is amazing lats, that are super thick. poor arms and delts with little detail and seperation. chest that is lacking in striations in the pick and good taper.
i think yates flexed and spread his back more in the front lat, while ronnie contracted his chest and delts.
im not a coleman guy, i can see that yates had a great back, but that is my honest opinion of the picks you posted. its really preference bt the two. i like the thickness and crazy taper ronnie has with great detail, over the dry, hard yates with great detail.
