I've got a Flex from 1996 and Flex has these huge calves. He must of had implants.
If your talking about the pic of him in awhite and black leotard, standing next to Lenda Murray and Paul Demayo, yes Flex's calves were off the hook in that pic. Escilene is more likely the culprit. Because Shawn made up that rumor, and it f'ed with Flex's head
Sorry for being a cliche... I was out that week with mono. 
So... Shawn having less sportsmanship than Tonya Harding, huh?
Has the ring of truth to it.
What Shawn did got Flex off his game, focusing his energy on Shawn and not training. Mind-games
