good question. It has been asked before. In fact, there is a thread right now asking why they gave ronnie the loss in 2006 but not in 2001.
The explanation for this is exceedingly simple: in 2006, Ronnie looked much worse than in 2001. Ronnie's main problem in 2001 was muscularity. At 245 lbs, he was take to the edge by a very conditioned Cutler. Now, this wouldn't be a problem is Ronnie had superb conditioning, but the bottom line is that he didn't. Add it all up, and Ronnie defeated Cutler because they had an equivalent number of symmetrical flaws, but Ronnie still had enough muscle mass in key areas, like quads and back, to defeat Cutler. Jay might have more mass that year, but the judges decided that Ronnie's combination of size with what they perceived as better separations made them give the nod to Ronnie.
Now, in 2006, Ronnie had a distended gut, was soft and holding water, lacked a lat and his overwhelming quad mass was gone - and Cutler's were also more cut. Ronnie still had his advantage in taper from the front, but Jay compensated by having better abs. From the sides, Jay had the flatter stomach. Now, what killed Coleman was the width and thickness of Cutler's back and Ronnie's lose of quad supremacy. Last year, Jay had finally matched Ronnie for lat width, but still lacked Ronnie's thickness. This year, he surpassed him in width and matched him for thickness. To summarize, Ronnie had all the weaknesses he had in 2001, but with none of the strenghs, so Cutler took him out
personally, I think the times of dynasties are over in the IFBB - they do nothing but loose fan interest and cause ticket sales to slump..
It can go either way: a dynasty can make it more interesting, because it creates a mystical aura of invincibility and godliness about the standard-bearer, or it can result in people losing interest. Regardless, I don't think it's political: there has been dynatical Mr.Olympias, but also those who only won it once.
Dorian got owned from almost every angle in 1994, and yet still was probably given perfect scores.
Why did he get owned? He was 262 lbs, adn hard as granite. His stomach was flat. His conditioning was off from the previous year, but that's not saying much, since the 1994 Shawn would also been considered "off" when compared to the 1993 Dorian. So it's irrelevant. Regardless, you may not like his structure and he definitely has bad taper in the relaxed round from the front. But the
fact is that he was the most muscular&symmetrical bodybuilder at that contest from most angles and while contracting different muscles, and while he wasn't as dry as in the previous year, he was still dryer than everyone else. His victory makes perfect sense from a bodybuilding judging criteria.

as the folks over on bodybuilding dungeon have said, "what a sham":
No, the shame is for a bodybuilder with a an alien queesn inside his abdomen, large un-manly glutes, terrible abs to win a Mr.Olympia. I'm not even bringing up calves.
