I don't think Dorian is owning anything due to the fact that he has so much less muscle. I know you are a big fan of Dorian's, but the only way he could have competed with Ronnie is by carrying 15-20lbs more muscle. Dorian was intrinsically no better than Ronnie and he simply didnt have enough muscle mass to compete with Ronnie. 
That same logic doesn't work due to the fact that Dorian appeared much, much larger than his weight suggested. This was backed up by the first hand account of Delta9mda who said Yates made everyone look like children, even despite being 20lbs less than Nasser. The
only version that would have made Yates look small is the 2004 Ronnie, but even then I am not so sure about this due to Ronnie's relatively poor condition, both in 2003 and 2004. Now, 98 and 99 Ronnie, no contest, Yates will carry more muscle and also appear bigger and denser. This is the main reason why I believe he would defeat a prime coleman.
