Not taking sides, but just because Ronnie says Dorian has the best back doesn't mean it's true. His opinion on the matter, even if that is what he thinks/thought, is no more valuable than any other objective, knowledgeable person's. So the argument that Dorian has the better back because Ronnie says so is baseless. It is no different than saying, "ND says Dorian has a better back so it must be true," or "Hulkster says Ronnie has a better back so it must be true."
And I agree that Ronnie easily has Stubbs. Stubbs has a comparable relaxed shot, but in the rear db Ronnie is the easy winner, as well as the rear latspread. Although Stubbs' rear latspread is good.
