Hey SMM,
I'm done with this thread but I'm going to show you some respect by replying to your comment.
Because you need to factor in Oliva's much higher bodyfat and water levels. The difference in weight is 17 lbs(240 lbs vs 257lbs) between Sergio and Ronnie at their respective primes, but when you take into consideration Oliva'a much higher bodyfat and water levels compared to Ronnie in his 1999 Olympia form, the actual advantage in muscle that Ronnie has over Sergio is closer to 30 lbs, and that reflects in much bigger and therefore wider deltoids.
I think you make an intelligent point about the weight difference. (Makes Sense.)
Sergio @ 240 had deltoid muscles close to the size of Ronnie's. Added muscle to the side
delts would make Sergio wider than he was back then but by the pictorial evidence, I believe Ronnie's clavicles are wider than Sergio's. (Taking into account that Sergio @ 240 already had deltoid muscles that came close to matching Ron @ his prime size wise.) (Not that Sergio's are narrow by any means.) Ronnie's clavicles are not as wide as Dillett's or Cutler's. (This is Gossip and Opinions and that's my opinion right or wrong.)
PEACE!!
