He wasn't a star in the states, Punk went to japan, sure, then he came to WWE, now he's a star. Johnny wasn't, these people don't watch japanese wrestling, and they certainly weren't watching japanese wrestling in 1995.
Also, why the fuck would Punk give the heel gm props for his japanese career that people don't even know about? That doesn't make sense.
The gimick is he's a corporate loser. Not he's a corporate loser who did very well in japan.
Rock buried Juvie as a loser, and he was on WCW when it was kicking Raws ass. That's just common wrestling talk.
Johnny had a brief and not very successful run in WCW (before it had taken off )and then went to japan, nothing about how well he did in japan is going to make him into a star here.
And in addition, Punk said he went to japan because he couldn't cut it here, so the entire point was that he had to go to japan. It doesn't matter that work rate was higher in japan to the audience who doesn't know or care about japanese wrestling.
Look at albert for christs sake, he went to japan and did well, they are trying to put him over by pointing out that he was so big there, and the audience doesn't care about him, and he's beating up Punk and Cena.
There's not point in trying to get it over that johnny was a big deal 20 years ago in another country, punk definetly shouldn't be doing it because he's the face and johnny is the heel.
