I'm pretty sure if that match ever did happen Austin would not do it unless he was closing Wrestlemania or on 2nd to last like he was in 2003 when he faced The Rock for the last time. I also don't see Austin winning the match against Punk if it is only going to be a one time deal.
2nd to last is still midcard, it's NOT good enough. Punk needs a MAIN EVENT. Fucking Miz has main evented WM and Punk hasn't. That's disgraceful, and that's coming from a Miz fan.
And of course Austin would win. He's not gonna put Punk over, Punk isn't a Superman character like Cena. I don't even think Vince would LET Punk beat Austin, even if Austin wanted to lose. I really don't believe it.
I understand wanting a match between them to be great, but saying it shouldn't happen because you think you know everything about how WWE would set it up is quite arrogant. I really don't think Austin is this weak mid card draw that you are so sure he is. He hasn't physically wrestled a match in almost 10 years. Austin's return to in ring action after a decade of retirement is a big ticket match and a hype train waiting to leave the station.
I didn't say he's a "weak mid card draw", he's not Sheamus or Randy Orton, obviously. When I say he's not a draw, I mean he's not a MEGA STAR anymore. And he's not. The Rock is. Even Cena is. Hell, at this point, even Lesnar, Triple H and Undertaker will draw more than Austin and it's not good enough, you can't main event a WrestleMania with the kind of business he'll bring in, it's not going to happen. I don't like it but I can acknowledge when somebody's run is over.
Would they make this match a main event if he was wrestling Cena? Yes, but not Punk. Not a chance in HELL.
