Ha ha ha, excuses why Dorian's triceps only looked good in the side triceps. Ronnie's triceps look good in every mandatory pose.
Dorian's triceps were thicker, denser and more striated than that of the 1998 and 1999 Olympia Ronnies. To make it even worse for you and your sophomori arguments, Dorian's triceps are also genetically superior to Ronnie's, since they insert lower in the tendom - the same reason why Ronnie's biceps are superior to Dorian's.
If you're talking about the 2003 Ronnie, then his triceps are just as thick a Dorian's - most of his arm size were biceps, so the difference in triceps mass was not that great. Ronnie's triceps might have been slightly bigger than Dorian's in 2003, but Coleman lost even more striations when compared to his 1998/9 forms. To make it even worse foryou case, Ronnie's gut distension is clearly visible in the side triceps shot you posted, and that flat out ruins the pose overrall, especially when compared to Dorian who had a flat stomach with visible serratus in that shot.

The triceps are not called into play and re not that relevant in any pose except the side triceps mandatory: it is here that triceps are judged on their own, and the bottom line is that Dorian takes it. I don't see how the triceps,in themselves,are relevant in mandatories like the abs-and-thighs, the rear lat spread, etc, but just to makeyou shut once and for all, I'll post some pics of Dorian doing mandatories where his triceps are clearly massive. Again, you lose.
