I saw Dexter and Jay in Sydney several years ago. Jay had good calves but Dexter had small ones. I have followed those two since and if Dexter had good calves he would probably have won the Mr Olympia.
Not everyone can get big calves. Matter of fact, in the old days that muscle separated the winners from the also-rans.
A guy like Ronnie shouldn't win Mr Olympia with a bodypart sub-standard. I have no idea what he does to those limbs but they lack separation and definition. Even the great Flex Wheeler showed up on stage one year with a vast gap in one calf. I am afraid that many blacks just won't have big calves. There are exceptions, of course, and Dillette, Oliva and Dickerson are a few.
Hey, I wonder what mystery boy Goatboy calves are like? No matter we aren't going to find out unless someone hires a private detective to track him down. Now that would be fun.
