Jones looks like a Zane in that B&W pic, but he really did have some decent size and good width. I haven't seen many pics of him, so can't say what he needs to improve on.
Rocco Jones needs a bit more leg size and overall thickness.
Thing is, he's claimed numerous times he won't rush things, he won't sacrifice his midsection and symmetry for rapid gains.
If he doesn't quit BB altogether, my guess is we'll see Rocco fighting it out with Sami and Heath for the number one spot in a year or two.
Although I don't think Heath is on par with Rocco, Heath's rushing things IMO.
