When people say a pro has poor genetics, they usually mean poor compared to the best (e.g., Jay compared to Big Ron).
Actually, since the retirement of Flex Wheeler, Jay Cutler is the most genetically gifted of all pros, even more so than Ronnie-and Ronnie has superb genetics. It's just that Ronnie is a decade or so loder than Cutler, so he has a lot more muscle maturity and density; nothing more natural. Oh, by the way, I'm not a Cutler fan.
