I was just reading the July 2009 edition of Muscular Development. Flex Wheeler does a critique of Jay and Wolf.
Flex talked about their contests bodyweights and bone structures.
Flex said that Wolf weighed 270lbs for the 2007 and 2008 Olympia shows. Flex said that Wolf felt that he over dieted in 2008 and shouldve weighed 285. (sounds like he was setting a bodyweight goal of 285lbs for the '09 Olympia)
So, in the end, I think Dennis weighed in at 285lbs at the 2009 Olympia (a bodyweight he was shooting for) and it landed him in last place.
I now think he felt embarrassed and didnt want to admitt his own faulty plan, so he blamed Chad for the poor placing. But, after reading Flex's words, I think Wolf was self deceived that he could weigh 285lbs and win the title.
