No
A was actling like a little child here
and was fearful
of looking mm in the eye
who would have ripped his head off
You have no idea how anybody was acting from that photograph, unless you were there in the room at the time....... and Arnold was afraid to look him in the eye? What other crazy observations can Mentzer fans mine from it? Because they certainly don't have a lot of fodder to choose from to make case for why Mentzer is better than Arnold.
Next you will be reminding everyone that Mike was a philosopher who liked to suck on Ayn Rands spiky cock (she had one you know) "so he's clearly more intelligent than Arnold wahhhh!" Who gives a shit they were bodybuilders so the only thing that matters is that Arnold kicked Mentzers ass hard on stage, and I think it's funny that Arnolds inferior and completely wrong training methods still allowed him to look much bigger than Mike after only 6 months of serious training.

Anyway I seriously doubt that Mentzer would have said all that much in front of weider and everyone, from all accounts he was pretty introverted. He was also 5'8 while Arnold was 6'2 so I don't know why Arnold would have been scared of him, he was just so much bigger as the photo's in this thread show.
A lot of people want to make out that there was this big rivalry between them but Mike wasn't even a blip on Arnolds radar, Arnold was just too successful, maybe Arnold could have been said to have had rivalry during is competitive heyday with Sergio Oliva and Sylvester Stallone at the box-office, but Mike Mentzer? Hardly. What did Mike ever achieve? They only met on stage once and then Mike talked shit about Arnold over and over to every 3rd tier magazine that would listen to him until the day he died, that's it just one small mans inability to move on in his life, talk about a storm in a teacup.
