That's all stuff that young kid from Austria heard A LOT of I guess.
Yes, but there's a huge difference between being 16 and 23. By the time he was 19 or so, Arnold looked pretty freaky and had one of the best builds in the world, not to mention he was also pretty strong. Dan Hill is much older and you can see he doesn't have the greatest arm genetics in the world, which throws off his overall look and is definitely going to affect his placings in contests.
I'm sure he's a nice guy. Just saying he's most probably not going to be a tier 1 or tier 2 pro with those arms.
