I see, I thought Glass trained and prepped, not just train, so McNeil did the prep... 
92/93 Flex was cut up like nothing else. Thanks to Joe, apparently from what I read, Flex wasn't willing to do all that again After his car crash, I firmly believe that Flex tried to overcompensate. There is a telling clue in his Mass Construction vid. He says that he went to see the 94 Mr. O and he felt that he couldn't compete with those guys....again, confidence is shook, 1st showing of the Flex Wheeler Lack of Confidence Syndrome (Something Phil Heath is showing signs of). Sure he could hang with them, he did it the year before.
It was Flex that told Dex to get in touch with Joe...
