Actually, in comparing a 99 Ronnie with a 93 or 95 Dorian, Dorian is more muscular. Both men are 257lbs, however Dorian is better conditioned and is 1-2" shorter (Ronnie is closer to 6').
Only pictoral evidence can account for your claims. Just because dorian was heavier doesn't mean he looked mroe muscular than Ronnie. And its not just sheer muscularity we're talking about here so much so the appearance of fuller, rounder, striated and vascular muscle...basically Ronnie is more aesthetic and displays better musculature.
so even if I were to take your word for it, that dorian was more muscular at that bodyweight, it still doesnt say much for why Ronnie still cruches him int heabck department in his 98-99 appearance. Its all about how it looks buddy
