Based on those criteria there you used for Samir, I don't see how you have Coleman in front of Yates. Yates' back is more detailed than Coleman and his lats are thicker and insert far lower.
There are things I like about both of their backs and I think it is close.
What pushes me over the edge for Coleman is the smaller waist and hips
that gives him an overall look from the back that Yates doesn't have.
Yates looks to me like a shredded powerlifter/bodybuilder whereas Coleman
from the back looks to me like a pure bodybuilders physique, although he still
looks powerful. This screenshots probably explains better what I'm talking about
than what I just wrote. (I also understand in this shot that Yates is probably standing
further away than Kevin to the camera.) We'd honestly have to see them side by side at their bests
to know for sure.
