Well it's not Lunsford. Too squat in body structure, torso is too long for too short-ish thighs, the thighs are splayed akwardly, and the lats don't originate far enough down around the hips and lumbar region.
I'll be controversial, and only because we're judging THESE pics (and not the BEST Ronnie pic). In this pic, it's clear to see Ronnie's left side is atrophying, throwing off his symmetry. The left lat has atrophied and pulled away from the origin around the spine. The infraspinatus has atrophied, as has the teres major. It throws off what should be a winning pose for him. And (this is my opinion), his glutes are too over-developed, throwing off his proportions on the pose. He has outstanding arms, bone structure, hamstrings...
That puts it between Heath and Yates in these pics. It's not one Heath can win. He shows well in the arms and calves, but Dorian's calves are as good/better. Phil's squattish bone structure makes Yates more aesthetic in the pose (Yates' longish legs, shortish torso). Heath's hams and glutes are better conditioned, but Yates' back is better conditioned and separated. Heath shows remarkable lat thickness top to bottom, but there's a lack of hardness there that betrays him. So, Heath loses to Yates.
1. Yates
2. Heath
3. Ronnie (a pic of a prime Ronnie instead of beat-up Ronnie would have likely won)
4. Lunsford
