I took a look at the photos of this show over at bodybuilding.com and Rusty had the best overall physique in my opinion. Best overall combination of shape, proportions, muscle size, cuts, aesthetic appeal on stage. He was definitely the best athlete (or bodybuilder if you wish) there.
I wouldn't be surprised if his career in gay porn and the fact that he wore a mustache (like the one on the film case in the just deleted thread) had a direct impact on his placings. It can be difficult to put somethings behind you, no pun intended.
Bodybuilding is a weird endeavor, its obvious that many of the competitors are gay, bi-curious, or willing to play gay for pay. Its obvious that a large percentage of the fans swing from the other side of the lake. What is strange is that despite this, when it gets out that these competitors are engaging in homosexual activity/ work they are black listed (or at least seem to be).
Examples:
Bob Paris
Chris Duffy
