Mike Matarazzo > Peter McGough.
I don't even necessarily agree with big Mike, but the endless Peter McGough quotes coupled with the contradictory argument that single opinions don't mean anything is doing my head in.
Anyway Ronnie could obviously be dryer but his lower body from the back is still possibly the most ripped ever, discounting Rich Gaspari or some of the really small guys. And as far as balance and proportion I honestly cannot see he's missing anything. Not only that but he's twice the size of everyone else! Levrone's got delt width and arm thickness, probably traps, but that's it, and he loses out in detail on arms and delts.
Bottom line that's a thick powerful physique!
