Gustavo Badell must have discovered an amazing stack because the difference in size from early 2004, to the Olympia, to the Arnold is nothing short of staggering. I'm suspecting GH, because the gut is popping out a bit, but that guy is looking quite freaky lately, and twice in a row he's beaten Lee Priest who continues to improve.
As for Dexter not looking 100% - I agree. The 2004 olympia was his best showing, and in comparison he's not as shredded as he normally is. Maybe the judges saw something we didn't see that was lacking in Cormier, rather than in Dexter. Who knows. He still looks amazing to me with his uniquely perfect symmetry.
