Ya i wondered what he'd think but he's too careful to publicly say anything anytime soon.
The best hint I think would've been his comments in the 90s about how the physiques then didn't look like bodybuilders more like powerlifters, alluding to Yates. Same would apply to Cutler i'm sure. This is exactly what is reflected in that link.
He liked the classic tapered look, so he'd go with Wheeler, earlier Coleman, Wolf, Martinez.
A couple of years ago when most of the previous Olympians were at the Olympia, i wonder what they thought seeing Coleman. Arnold on stage with Ron would've hated the gut but at the same time must've been blown away with the size.
