I remember back in 2004 or 2005, somebody who saw both Ronnie and Jay up close several times said that Jay had naturally wider shoulders than Ronnie. Ronnie had huge deltoids, but just standing there, Jay’s shoulder width looked noticeably wider than Ronnie.
And this same person said that up close, Jay looked wider than Marku Ruhl too.
We see pictures of these pro’s onstage... with potentially lots of oil in there shoulders. But up close, you can see the real width.
